Having a [[{{Heroes}} Superhero]] parent is like being BlessedWithSuck. There's the bi-weekly kidnappings, frequent ParentalAbandonment, being constantly lied to if your parent has a SecretIdentity, being ''forced'' to lie to [[SecretKeeper maintain your secret]], and constant worry that your parent(s) or you will be killed by a vengeful [[{{Villain}} supervillain]]. But look! You can fly!

Normally, heredity is a messy affair; it's often described as a game of chance. Thanks to Darwin, Mendel, Watson and Crick, it can be explained a good deal better, but much like AIIsACrapshoot, what traits a child will inherit from each parent are mostly random. Not so with superpowers. Children of "supers" can have a limited number of things happen:

# Develop identical powers to their parent(s).
# Develop radically different (and usually [[SuperpowerLottery insanely powerful]]) powers from the parent(s).
# Develop powers that are a twist on their parent's powers, or a combination, if both parents are supers (though this happens much less often than the above two).
# Inherit their parent's ''skills''; see LamarckWasRight.
# Inherit no powers or skills at all, then eventually manifest them.
# Inherit no powers or skills at all, for keeps this time; see MuggleBornOfMages

Super-power inheritance tends to happen more often than could be ascribed to chance; a non-powered child of even a hero and a normal person is an exception. Super-powers seem to be "more dominant than dominant" (more common than genetics should allow).

If a parent's powers are caused by [[LegoGenetics gene splicing]], or from being born a [[{{Mutants}} mutant]] or [[HalfHumanHybrid part]] or full [[HumanAliens alien]], then it gets interesting. Specific powers actually have a higher chance of ''not'' being inherited. In such cases, the child usually gets a completely different power, or at best one that's only tangentially related. This becomes much likelier if both parents have different powers. Only occasionally will they just have a combination of their parents' powers; this tends to happen if the parents' powers are very simple, or if the series was designed around the child, and the parents were brought in as part of the BackStory as a SecretLegacy. If this happens often enough, it may be [[RetCon revealed]] that all the powers of that family are just different expressions of the same gene as a MetaOrigin.

If only one parent has powers, however, the child's powers are much more likely to be a straight copy of those, though often at a higher level. This may encourage the writers to give that power its own MetaOrigin.

[[folder:Anime & Manga]]
* ''Anime/DragonBallZ'' repeatedly shows that hybrids of humans and super-powerful aliens produce insanely powerful offspring. Lampshaded by Vegeta, when he notes that he trained intensely to unlock his Super form, while his hybrid kid can do it for fun. If a child is conceived after the father has unlocked said Super form, that child will be able to do so with essentially no effort, in a case of LamarckWasRight. If the child was born beforehand, it's quite a bit more difficult. They're crazy powerful regardless, though. The only real exception to this out of ALL the half-saiyan children is Vegeta's daughter Bra, who he apparently chooses to dote on rather than train.
** Before any of that, this trope is PlayedForDrama in the Cell saga, where the BigBad was created from the genes of [[LegoGenetics most of the heroes]]. This gave him all of their strengths and their deadliest techniques.
*** In the future, descendants of Vegeta and Goku don't even realize the significance of their Super forms other than noting their hair turns yellow.
** The author admitted he had no idea what to do with or even how to handle a female Super-Saiyan so he just ignored Bra.
* In ''Manga/HunterXHunter'', insane Nen-potential seems inherited just like insane physical potential.
* Tenchi Masaki of ''Anime/TenchiMuyo'' is slightly over one quarter Juraian (his father happens to be a descendant of his maternal grandfather). Juraian's are an alien race with a tendency to develop Jedi-like powers with training (the royal family being stronger as well). He's also ''the'' most powerful "Juraian" in existence; capable of manifesting three "lighthawk wings", one of the most powerful defensive/offensive attacks known. A typical Juraian ''space ship'' is capable of manifesting only ''one''.
** OVA Tenchi is most likely disqualified from this as [[spoiler:he's the avatar of his dimension's ''god'']]. However, the one from ''Anime/TenchiUniverse'' more than qualifies as it's said that his own Juraian power was passed down from his mother, who was pretty damn powerful in her own right.
* In ''Manga/RanmaOneHalf'', the Musk Dynasty bore offspring through wild, powerful animals that had been thrown into the Spring of Drowned Girl, thus turning them into women. Their children would then inherit traits exhibited by, or closely related to, their mothers' natural form. Hence, Mint's superhuman scent, hearing, and speed (born from a wolf); Lime's grotesquely overpowered physical strength (born from a tiger); and Herb's ability to fly and discharge [[BattleAura his ki]] in devastating streams (born from a dragon). One episode of the anime hinted that children of a cursed parent will inherit that parent's curse--but that episode was all one of Ranma's nightmares, so it's not canon.
* Type 1 was intentionally done by [[WarriorPrince the Kings of]] [[TheEmpire Ancient Belka]] in ''Franchise/LyricalNanoha''. The modifications on their bodies were not only meant to turn them into [[PersonOfMassDestruction Persons Of Mass Destruction]], but to force the powers they gained unto their future descendants as well.
* A number of ninja clans in ''Franchise/{{Naruto}}'' have special genetic powers referred to as "kekkei genkai", or "bloodline limit". These include eyes that can copy others' abilities, being able to manipulate and regrow your own bones, any ElementalPowers which are formed by combining any two of the basic five elemental affinities (for example, Water + Wind = Ice), etc. There are also abilities that ''seem'' like this, but are actually just well-kept [[TheClan clan]] secrets, such as the Nara clan's ability to manipulate shadows.
** However, genetic powers aren't always passed down. The best example of this is the First Hokage's [[GreenThumb wood release]], which was entirely unique to his DNA, with none of his descendants inheriting it. Another partial example would be the Fourth Kazekage, since only his youngest son inherits his power of magnetism.
** Unlocking the Rinnegan, [[spoiler:the ultimate form of the Sharingan]], requires combining the genes of the Senju and the Uchiha clans, the respective descendants of the Sage of Six Path's two opposing sons. [[spoiler:Madara Uchiha awakened his Rinnegan by stealing a small piece of Hashirama Senju's flesh and grafting it onto his own body.]]
* In ''Manga/BoboboboBobobo'', Maitel is a 3rd cousin of [[Myth/ClassicalMythology Medusa]]. Naturally, this means he can turn people to stone too.
* [[BadassFamily Joseph Jostar]] from ''Manga/JoJosBizarreAdventure'' could use his grandfather's sun channeling abilities from a very young age, although he had to train them for them to be effective against [[ReligionOfEvil Pillar Men]].
* ''Manga/{{Bleach}}'':
** Quincy powers are hereditary, leading to an clan-wide obsession with bloodlines.
** Ichigo and Karin can see ghosts, Yuzu can see faint outlines of them, and Ichigo eventually became a Shinigami with an extremely high amount of spirit energy. Why? [[spoiler:Their father Isshin is a retired Shinigami, and has all the same powers Ichigo does, at a Captain's class. Ichigo also inherits hollow and Quincy powers from their mother's side that make his attempts to master his abilities very complicated.]]
* Weapons in ''Manga/SoulEater'' come about in this way, thanks to the 'bloodline' of the original experiments. It's possible for a weapon to show up in a family that hadn't had one for a very long time, which we see is what happened with Soul Eater himself. For some reason, the Nakatsukasas had come to expect that the eldest child would inherit the Morph Weapon abilities. When this did not happen, things did not end well. Kid falls definitely into the 'will eventually inherit' category, as BREW so helpfully showed off.
* While ''Anime/TigerAndBunny'''s WordOfGod says that NEXT abilities aren't genetic, it's certainly telling that [[spoiler:the two superheroes who were fathers (Wild Tiger and Mr. Legend) ended up having superpowered children (Kaede and Yuri Petrov).]]
* Subverted in ''Manga/PlusAnima''. People with Anima power are believed to have Kim-un-Kur blood in their veins. [[spoiler: In reality, children gain the ability to turn into animals they see during their near-death experiences.]]
* ''Manga/AttackOnTitan'' has the [[spoiler: Ackerman]] family, who all gain superhuman physical ability in times of emotional distress. There's also an unusual case in which the superpower isn't so much an advantage as lacking a disadvantage; there is a power that can control people, but only works on particular bloodlines, with people sufficiently unrelated to those bloodlines to be immune being rare. [[spoiler:Members of the Eldian race are the only ones that can become Titans and Titan Shifters.]]
** The [[spoiler:Ackerman]] family is said to be a result of [[spoiler:"titan science", implying that they're human-titan hybrids (despite titans being human to begin with) in some way.]]
* Implied with the title character in ''Anime/ProjectAKo''. A-ko's parents appear to be CaptainErsatz versions of Comicbook/{{Superman}} and ComicBook/WonderWoman, which would explain her extraordinary strength.
* ''Manga/MyHeroAcademia'': Every Quirk (superpower) is hereditary, with a child having the potential to either inherit the power of one of their parents (Type 1) or develop a whole new Quirk that is a combination of both powers (Type 3). Being born without a Quirk is also possible (Type 6), but rare, and it's even rarer for someone to develop a Quirk completely different from their parents' through a genetic mutation (Type 2).

[[folder:Comic Books]]
* The children of Comicbook/FantasticFour members Reed and Susan Richards show two variations. Their daughter, Valeria, has been shown in a future timeline to have a more advanced version of Susan's {{invisibility}} powers (other [[AlternateUniverse alternate]] Valerias have been shown with a variety of powers), whereas their son Franklin is sort of...intermittently [[RealityWarper omnipotent]].
** Valeria is currently a super-genius; three years old already Reed-class. Franklin is currently depowered after the last time he pushed his omnipotence into overdrive. At his maximum, he is potentially one of the most powerful beings in the universe; characters who can make Galactus sit up and beg were afraid of him for a while. When he has powers, there's usually a RestrainingBolt (imposed by him or others depending on the timeline) on them that limits him to helpful but not god-tier psychic abilities.
* [[Comicbook/GoldDigger Gina Diggers]] is a definite type 5. Despite being the only daughter of Earth's most powerful aura mage and Jade's greatest warrior she has absolutely no talent for magic or fighting whatsoever. (Alternatively, given her certified super-genius [[ScienceHero action]] OmnidisciplinaryScientist status a case could be made for her being a type 2 who simply doesn't stand out ''quite'' so much due to already living in a WorldOfBadass.)
* Descendants of the ComicBook/{{Flash}}es universally inherit SuperSpeed; Franchise/TheDCU's [[MetaOrigin "meta-gene"]] was called in to explain this. Many other DC characters avoid this trope by having their successors or apprentices come with their own origins.
** This was played with when Flash Wally West fathered twins. Although both had powers based on speed, his son's ability was [[SuperStrength super-accelerated growth of muscle tissue]], and his daughter could [[IntangibleMan vibrate through objects]]. Now she has basic SuperSpeed and he's unpowered.
*** You can always say in this case that [[AWizardDidIt the Speed Force did it.]]
** Another example of a superpowered lineage could be found in the DCU ''Comicbook/{{Manhunter}}'' series. Kate comes from a long line of metahumans. Her great grandfather Hugo Danner, grandfather Arnold "Iron" Munroe and father Walter Pratt were all superhuman. While Kate herself is not fully-superhuman, she is unusually strong and tough and it is implied that she is a borderline metahuman. Her son Ramsey inherits powers that easily exceed any of his ancestors. He is also an extremely rare fifth generation metahuman.
* Blindside of the DCU's ComicBook/RelativeHeroes apparently inherited the ability to turn invisible from the Golden Age hero the Invisible Hood, and Hood also passed his ability and hero name on to a confirmed great grandson. Blindside's status as twice orphaned means and the fact that his last name doesn't match up (both Hoods were Thurstons, Blindside's name is Tyson Gilford) means he has trouble confirming this.
* The main characters of ''Comicbook/{{Runaways}}'' tend to have superpowers corresponding to those of their parents. Many of these "powers" are magical or technological gifts.
** In ''Comicbook/{{Runaways}}'', Molly Hayes initially appears to have not gotten the mutant gene despite her parents both having it. Early on in the story however, she is discovered to have super strength (while both parents had mind controlling powers, and ''her'' strength turns out to be psionic in nature). Karolina has exactly the same alien powers as her parents which her mother points out means that none of them can hurt each other. Chase is the son of two brilliant MadScientist GadgeteerGenius types, but his abilities run more to minor cleverness, street smarts and punching things. Gert has a pair of travelling also mad scientists (but more biology based) for parents and though she is gifted with there intelligence, her power is actually something they engineered for her - being psychically linked with a bio-engineered Deinonychus (think ''Franchise/JurassicPark'' Raptor).
* The comic ''Comicbook/{{PS238}}'' both uses and subverts this trope. The premise of the comic is an elementary school for children with superpowers, many of which have heroes as parents. The main character, however, is a new student, the child of two of the most powerful heroes in the world, who has no powers whatsoever. (His parents are [[StageMom simply convinced that their son's powers have not yet manifested, as he will be as powerful as they are]].) As the story has developed, it is becoming increasingly clear that the character is the school's BadassNormal in training.
** This gets deconstructed later [[spoiler:by "BigBad" The Headmaster, an anti-metahuman WellIntentionedExtremist, who considers superheroics a form of evolutionary mutation: Like all mutations, they want to spread, hence why "classical" superheroics are actually a form of courtship display meant to showcase the superpowers of the individuals involved. He argues that eventually, competition for mates, evolution of powers and crossbreeding of metahuman with metahuman will lead to the piling on of powers over several generations, creating more and more powerful superpowered children until eventually a GooGooGodlike scenario and the probable destruction of planet Earth. An alternative scenario shows up on planet Argos, where the FlyingBrick power set became dominant and eventually [[InferredHolocaust led to a "cull" of all other metahuman powers]]. Argos is a permanent feudal society, with Flying Bricks as nobles and non-powered "Softies" as a permanently repressed underclass. The noble houses keep the Flying Brick powers stable through {{Arranged Marriage}}s between houses.]]
* The ComicBook/XMen had mixed up examples of 1 and 2; while Jean Grey (psionics) and ComicBook/{{Cyclops}} (EyeBeams) gave birth to two (or three, depending on how you count) of the most powerful psychics in existence, ComicBook/{{Magneto}} (with powers of magnetism) fathered a [[SuperSpeed speedster]], [[WindsOfDestinyChange a probability manipulator]] and (via {{Retcon}}) a magnetism user like him.
** At least one version of [[ComicBook/ScarletWitch Wanda]]'s origin had it that her "natural" mutant ability was some form of energy manipulation, like her father, but she "attuned" to the magical energies around Wundagore Mountain, resulting in her "Chaos Magic". (This was before [[RetCon Dr Strange said there was no such thing as Chaos Magic]] and [[{{Retcon}} then denied that he would ever make such a claim, OF COURSE Chaos Magic is real]]).
** ComicBook/{{Wolverine}}'s recent {{Retcon}} backstory posits that he is descended from two powered families, one with bone claws and one with a HealingFactor. Nightcrawler is likewise (supposedly) the child of an ages-old mutant clan with interdimensional powers, and Angel is implied to be from an angel-like mutant bloodline as well.
** Clan Akkaba are descendants of ComicBook/{{Apocalypse}}, and each member has inherited variations on his powers. The greater families, including the Slades, have a weaker version of Apocalypse's shape-shifting and longevity, and a minority also possess his grey skin. The 'Lesser' members have different and unique powers, such as Jack Starsmore, who can instead breathe fire. Rarely shapeshifting members randomly gain additional mutations, such as Frederick Slade, who has pink hair, solid green eyes and [[spoiler: teleportation, shared with his descendant Blink]]. Chamber's powers as a psychic furnace are very different to his ancestors Jack Starsmore and Apocalypse.
** In ''ComicBook/YoungAvengers'', on the other hand, the "brothers" Tommy and Billy apparently got the same powers as [[spoiler:their "mother" Wanda ( it's complicated) and uncle Quicksilver - Tommy has superhuman speed and Billy can manipulate reality by expressing a desire for it. Any powers from their "father" the Vision seem to be nonexistent, possibly because Wanda "gave birth" to them herself]]. Cassie Lang shares the same growth powers as her father Scott, however this was from her stealing Pym particles and not inheritance (her father's superpowers weren't genetic). While Patriot has no powers from birth, he does get superhuman strength from his grandfather (formerly one of the Captain Americas) via blood transfusion. FF foe the Wizard is a MadScientist with no powers, but being around gravity-manipulating technology most of his life lets him have a daughter who controls gravity innately.
** Averted by Mystique and Sabertooth's son Graydon Creed, who is a [[MuggleBornOfMages baseline human born to two mutant parents.]]
** ComicBook/{{Quicksilver}} and the [[ComicBook/TheInhumans Inhuman]] princess Crystal's daughter Luna subverts this. The X-factor and Inhuman genes ''cancel each other out'', leaving Luna an effectively baseline human. Her dad, driven crazy (well, crazier) by the loss of his powers thanks to M-day, exposed her to a heavy dose of Terrigen Mist to correct this "error". Thankfully, it worked. Luna survived (though she developed a bit of an addiction to the Mist) and gained [[TheEmpath empath]] powers.
** One of the consequences of M-day was that mutants could no longer have mutant offspring. They could still have children, but the children would be baseline humans.
** A possible future introduced [[MeaningfulName Ruby]] Summers, daughter of Cyclops and Emma Frost. She has her father's eye beams and has also inherited her mother's "secondary mutation", only instead of diamond she turns to ruby, reflecting her father's ruby-quartz visor.
** In stark contrast to Graydon Creed mentioned above, Mystique's [[spoiler:and Wolverine's]] future son Raze has both of his parents' power-sets.
* In ''ComicBook/RisingStars'', it's explicitly stated that the children of the Specials inherit no powers.
* The ''ComicBook/WildCATs'' are all [[HalfHumanHybrid descendants of]] the Kherubim and/or the Daemonites, super-powered alien races, and inherit their powers-- since both races have a vast array of potential powers, the humans usually only get a random fraction of them.
* ''ComicBook/{{Gen 13}}'' and their EvilCounterpart team ''[=DV8=]'' inherit powers from the genetic SuperSoldier project that produced Team 7 and other gen-actives. Generally, these powers have nothing to do with their parents' powers (except the time [[PlayingWithFire Burnout]] inherited his father's MindControl powers for about a week).
* ''ComicBook/{{Zenith}}'' is a slight subversion; he does get his parents' powers, just not ''all'' of them, and they don't work all the time.
* Marvel's ''[[ComicBook/TheEternals Eternals]]'' avert this; they can breed with mortals, but the kids are just normal humans. This plays a part in Ikaris' tragic BackStory (here's a hint; he took the name Ikaris in honor of his late son).
** Eternals breeding with Eternals rarely produces offspring, but they are full Eternals--except for the Titanians, who originally only had half the power of the Earth Eternals, and whose current population are descended from both sides of the "family", resulting in wildly varying power levels and longevity. Then there's the Ritter twins, children of an Eternal and a Deviant (another offshoot of humanity with constant mutations); they appear as normal humans but can FusionDance into either one or two Eternal-powered beings, DependingOnTheWriter.
** Comicbook/{{Thanos}} wields far greater power than the average Titanian Eternal due to a mutation that also made him look like a Deviant. His mother tried to kill him when he was born since she (rightly) believed he would be a monster later in life, but his father spared him because he (also rightly) thought an Eternal/Deviant mutant had great potential.
* Lampshaded in ''ComicBook/{{Invincible}}.'' Invincible's super-powered alien dad explicitly has genes that beat up and take over the genes of whatever he mates with, creating offspring that are almost identical to himself, powers included. Case in point, he also [[HotSkittyOnWailordAction mates with a humanoid praying mantis girl]] and produces a child who looks perfectly human except for his purple skin.
* ''Comicbook/{{Superman}}'':
** The Man of Steel has no canonical descendants, though the issue has been explored in many [[{{Elseworld}} "imaginary" stories]]. Classically his children with a human wife have all his powers at half power level. The [[ComicBook/SupermanAndBatmanGenerations Generations]] storyline affirms this with halving occurring with each successive generation. One Elseworlds had one of Kal-El's Ancestors land on Earth and take over, with each successive generation being less powerful to the point that Kal-El himself had no powers and his father was barely superhuman.
*** The current ''ComicBook/SupermanRebirth'' story subverts this, with Jon Kent being both canonical and potentially even more powerful than Superman himself.
** More recent examples of his offspring include a child of Superman and Wonder Woman who ended up being an alternate version of the Phantom Stranger. In ''ComicBook/DCOneMillion'', his offspring apparently retain their powers through successive generations and gain new ones by intermarrying with various species including a 5th dimensional being, forming a Superman Dynasty. Superman himself returns in this timeline after hundreds of thousands of years transformed by exotic energies and gaining the ability to bestow additional powers on his offspring. The Superman of the 853rd century, a direct descendant of Superman, is like our Superman [[UpToEleven on steroids]].
** The aforementioned ''Generations'' storyline has an odd instance of a type 5 in Superman's son Joel Kent who would have had his powers had he not been exposed to Gold Kryptonite in the womb. Much to Joel's bitterness and dismay, his younger sister was not exposed and ended up a type 1.
** Hinted at in another 'maybe' story. Superman officially [[spoiler:died ten years before the story begins. While a reporter is talking to a now-married Lois Lane for an anniversary article on events, her baby boy is seen crawling around. After her husband comes home, the baby is playing by the fireplace with a piece of coal. The next frame shows the baby in the same place playing with a diamond. No, they did not find a body ten years before.]]
** In the ''New 52'', Superboy was revealed as the clone of the future son of Superman and Lois Lane, Jon Lane Kent, who was raised by a metahuman hater called Harvest to be a LivingWeapon - and both he and Superboy were, for whatever reason, [[PsychicPowers massively powerful psychics]], though they were hinted to have more classic physical superpowers too. No one had any particular idea as to why.
* [[Comicbook/IncredibleHulk The Hulk's]] kids are an interesting case. His son, Skaar, inherited both his parents' power sets - giving him the power to [[DishingOutDirt control the earth]] in addition to the Hulk's powers. His twin brother Hiro-Kala only got the tectonic powers. His daughter Lyra, created via genetic engineering, got only a measure of the Hulk's superstrength; instead, she developed the ability to attune herself to gamma radiation - in combat, she can almost always position herself exactly where she needs to be. Unfortunately, thanks to deliberate tampering in her creation, the angrier Lyra gets, the ''weaker'' she gets.
** It's later revealed that Hiro-Kala [[spoiler:is a Hulk as well, but has never hulked out. And his transformation is triggered [[PowerOfLove by love]].]] Also, his tectonic abilities are absurdly powerful by his race's standards.
** And it turns out all Gamma mutates are descended from a single common ancestor who had the latent genetic trigger that causes gamma radiation to grant superpowers as opposed to nasty radiation sickness.
*** Not all; Bruce Banner's mentor, Professor Gregory Crawford, who discovered said genetic trigger while examining Bruce's blood, found a way to copy it through genetic manipulation, which he used to turn himself into the Gamma mutate Ravage. It's also suggested that the ComicBook/RedHulk and Red She-Hulk didn't have the genetic marker themselves, and were only created and stabilized after significant genetic modification.
*** Betty Ross (Red She-Hulk) has the genetic marker, as Modok had previously turned her into the gamma-mutate the Harpy to use her against the classic Green Hulk (her Red She-Hulk status being a result of combined gamma and cosmic ray exposure).
* In the case of ComicBook/TheSavageDragon, the main character's son Malcolm directly inherited full-power versions of both parents' powers, which isn't so surprising if you know that Dragon's powers [[spoiler:run in his family's dynasty]]. His mother's electrical powers were given to her later in life, so they must have caused genetic changes, thanks to [[UsefulNotes/TheGoldenAgeOfComicBooks Golden Age]] villain [[CaptainErsatz Doctor Nirvana's]] experiment.
** This series has a ton of examples of this trope, as it's been running in real-time for nearly twenty years, leading to many second-generation characters appearing constantly.
* ''ComicBook/{{Planetary}}'': It is explained Century Babies all have extended lifespans in addition to their abilities. Their children will also inherit the extended lifespans, along with abilities of their own, as evidenced by Jakita Wagner and Anna Hark, but not William Leather(whose mother cheated on his father, a Century Baby).
* When a character in the ''Literature/{{Lensman}}'' series has the last name "Kinnison", you can be sure they're going to kick ass. They may die in the process, but ass ''will'' be kicked in the meantime. Kimball Kinnison (the hero of ''Grey Lensman'' and ''Second-Stage Lensmen'') eventually marries Clarissa [=MacDougall=], a descendant of Virgil Samms, the eponymous ''First Lensman''. Their kids are the ''Children of the Lens'', and they're explicitly stated to be the most powerful minds in the Galaxy, exceeding even the Arisians who ''created'' the lenses. To give just one example, while son Christopher is given a Lens, his four sisters are not ... instead, they realize they might be useful occasionally, create them out of thin air using sheer mind power, and then dissolve them again the same way until they're needed.
* ''ComicBook/SpiderGirl'': May "May Day" Parker is the daughter of [[ComicBook/SpiderMan Peter Parker]], and not only did she inherit his powers ([[PubertySuperpower that didn't manifest till her teens]]) but also his sense of humor, fight banter, and his academic skills. However she's not exactly like him as she got her mother's good looks and social skills.
* ''ComicBook/{{Family}}'': The mafia have superpowers thanks to the 'bloodline', hence why they favor Sicilians marrying each other to not dilute it.

[[folder:Fan Works]]
* A common theme in [[NextGenFic Next Generation Fanfics]].
* ''Fanfic/LastChildOfKrypton'': In this crossover [[spoiler:Yui Ikari finds Jor-El's rocket with a sample of his material genetic]]] -in the rewrite it is [[spoiler:a sample of ''[[Franchise/{{Superman}} Kal-El]]'''s DNA]]- and she [[spoiler:modifies her unborn baby with kryptonian DNA.]] When Shinji grows up he develops Superman powers.
* ''Fanfic/SOE2LoneHeirOfKrypton'': It kicks off the entire plot. Long story short, [[spoiler:''[[Franchise/{{Superman}} baby Kal-El]]'' dies when his rocket crash-lands on Earth,]] and his DNA is used to fertilize one of the Kyoko's eggs when she got an in vitro fertilization. When Asuka was a teenager she started to develop kryptonian powers.
* Auric powers in ''RolePlay/WeAreAllPokemonTrainers'' are normally conferred by genetics, though they can skip generations, as was the case with [[MuggleBornOfMages Dune.]]
* In ''Fanfic/ChildOfTheStorm'', Harry starts developing SuperStrength, inherited from his father, and PsychicPowers, inherited from his mother thanks to her relation to the Grey family - though Lily didn't have them herself. They are... impressive. Put it this way. Jean is the strongest psychic ever born [[spoiler: (jointly with her twin sister, Maddie Pryor, as it turns out)]]. Harry's the only other person who's even in approximately the same weight class (though as the sequel demonstrates, Professor X's skill and experience means that he could take them both to the cleaners).
** [[ComicBook/WonderWoman Diana]] inherits her strength from her father, said father being Hercules. No one's entirely where the flight came from, though. Or the empathic abilities.
** Carol has inherited [[spoiler: the super soldier serum from Steve,]] something hinted at, then confirmed in chapter 75.
* ''[[https://www.fanfiction.net/s/10129058/1/The-Snow-Queen-and-the-Ice-Demon The Snow Queen and the Ice Demon]]'' explains Elsa's [[AnIcePerson cryokinesis]] by making her Loki's daughter, whose Jotun blood attuns him to ice.
** The sequel ''[[https://www.fanfiction.net/s/12257555/9/The-Ice-Demon-and-the-Captain The Ice Demon and the Captain]]'' introduces Pietro and Wanda Maximoff, also descendents of Loki by their father Erik and possessed of latent powers. Erik and Pietro are also mentioned having inherited Elsa's MysticalWhiteHair.
* [[WebAnimation/{{RWBY}} Cinder, Jaune, and Ruby]] are all prominent examples of this in ''Roleplay/LordsAmongTheAshes''.
** Cinder carries the Blood of Destruction, an inheritance passed down in her line since before [[TheRevolutionWillNotBeCivilized they were cast from power by those who had placed them there.]]
** Jaune carries the Blood of War, a power cultivated in his line [[PragmaticHero in an attempt to avoid the self-destructive nature of others without losing any of their might.]]
** Ruby carries the Blood of Death, a legacy bestowed upon her line for the sake of [[HunterOfMonsters destroying the Grimm]] [[HeWhoFightsMonsters but which may lead to their own destruction in the end.]]

[[folder:Films -- Animated]]
* ''WesternAnimation/TheIncredibles'': Mr. Incredible, with his SuperStrength, and Elasti-Girl, with her elasticity, get married and have Dash, a {{Super Speed}}er and Violet, who has {{invisibility}} and force fields [[spoiler:and Jack-Jack, who seems to have a [[ComboPlatterPowers full combo platter]]]].

[[folder:Films -- Live-Action]]
* A type 2 in ''Film/{{Looper}}'', though not exactly "super powerful" in the beginning.[[spoiler: The resident ChekhovsSkill in the film, the mutant's telekinesis, is fairly common and doesn't really impress anyone. However, Sara has a notably stronger version of it, and her Cid - being her child and that of another mutant - has that power turned UpToEleven.]]
* In ''Film/X2XMenUnited''; the mutant gene is said to be passed down from the father (but not explicitly stated to be located on the Y chromosome). Though given the tension of the scene, it seems likely that Pyro was simply exploiting Mr. Drake's ignorance to make him squirm.
* ''Film/SkyHigh2005'' goes with the fourth option ''twice''. After spending a long while thinking he would never develop powers, the main character inherits his father's SuperStrength and his mother's {{Flight}} powers separately (both were DieOrFly situations, the second a SuicidalGotcha using flight). The bus driver, and only other person on record to have super parents and not get powers, just exposed himself to toxic waste and grows 50 feet tall on demand. Nurse Spex also states that sometimes powers just aren't passed on at all.
* ''Film/NecessaryEvil'' seems to be reaching for both 4 and 5, with the brothers.
* Ang Lee's Film/{{Hulk}} gets the same [[LegoGenetics aftermarket add-ons]] as his father, which Banner Sr. spliced into himself in a failed attempt to make a SuperSoldier. It takes both [[ILoveNuclearPower Gamma rays]] and {{Nanomachines}} to finish the job.
* The Disney movie ''Film/UpUpAndAway'' involves a boy named Scott whose parents are Bronze Eagle and Warrior Woman. Bronze Eagle can fly, and Warrior Woman has super-strength as well as a super-fast motorcycle. His big brother, Silver Charge, has super-speed and electrical manipulation. His little sister has x-ray vision and EyeBeams. Even his grandparents on his father's side have super-strength/flight (grandfather, Steel Condor) and VoluntaryShapeshifting (grandmother, InformedAbility). Scott's problem is that he's quickly approaching his 14th Birthday, and he has yet to develop any ability. 14 is the cut-off for a super. If he doesn't get an ability by that time, than he's just a {{Muggle}}. To that end, he decides to fake having super-strength (by rigging a door to fly off its hinges) and flight (by throwing a ball at a tree and hiding). In the end, though, it's his normalcy ([[spoiler:and immunity to [[KryptoniteIsEverywhere aluminum foil]]]]) that ends up saving the day.
* In ''Film/{{Push}}'', children of psychics tend to inherit their parents' abilities, sometimes to a greater extent (although the reverse can be true as well). For example, Cassie is a watered-down version of her extremely powerful mother (a [[{{Seer}} Watcher]]), while Nick is a more powerful [[MindOverMatter Mover]] than his father was (at least once he has some practice). The [[TheTriadsAndTheTongs Triad]] boss's sons have inherited his [[MakeMeWannaShout Bleeder]] ability (although his is more powerful), but his daughter is actually a pretty good Watcher (possibly, her mother was one as well).

* In Creator/StephenKing's ''Literature/{{Firestarter}}'', the young female protagonist inherits powers from both of her parents, ''squared'' - despite the fact that their superpowers were caused by an experimental drug, not genetic tinkering.
* Avoided in Creator/CharlesStross' ''Literature/TheMerchantPrincesSeries'' - the single superpower is caused by a recessive gene, and the inheritance is consistent.
* Inverted in the ''Literature/WildCards'' anthology series. Superpowers are caused by the Wild Card virus, which can be passed on by either parent, and is always passed on if both parents have it. However, only 1% of infected people become super powered "aces," regardless of how they were infected. This means the child of two aces is 9% likely to become a deformed mutant, and 90% likely to die a horrible death.
** One ace character must break off his engagement to his childhood sweetheart when he finds out she has the virus too-- and he [[SecretIdentity can't even tell her why]].
** There is one case of an ace having a daughter with identical powers, but this is explained by saying he psychically manipulated her genetic structure in the womb. If there was a trope for Suspiciously Specific Superpowers, that guy would be the Trope Maker.
** The Psi Lords of Takis have inheritable powers, which is to be expected since they are the products of a SuperBreedingProgram specifically geared towards perpetuating their telepathic abilities into successive generations. The traits appear to be dominant, but can still breed out over generations. For example, Dr. Tachyon's grandson (by way of ordinary humans) Blaise exhibited stronger-than-normal mind control, but no other telepathic abilities, suggesting that Psi Lord powers are not all derived from a single gene.
* In ''Literature/HarryPotter'', it's quite common for a magical child to be born to two {{Muggle}} parents, which ''Literature/TheTalesOfBeedleTheBard'' explains as so-called "Muggle-borns" actually having wizarding ancestors somewhere in the family tree. Which seems to indicate that magic is a recessive trait. However, nearly every person with at least one magical parent is magic themself, and [[MuggleBornOfMages Squibs]] exist but are incredibly rare. This doesn't fit with a recessive allele, but a dominant one doesn't actually make ''more'' sense. FanWank abounds, naturally, most of which points out that [[AWizardDidIt this is magic we're talking about]].
* A version occurs in one of the ''Serendipity'' books when a pegasus mare mates with a mortal stallion. When she turns out pregnant, a wise old mare explains that the child could be born with either legacy. Turns out he's born with tiny, tiny wings, obviously unable to let him fly - but still the mother thinks perhaps they'll grow. However, by the time she must leave (for if she stays, she too will lose the ability to fly), the wings are as small as ever. She wings away into the clouds, trying to ignore the cries of her terrified child. [[spoiler:But the series being full of magic and generally using happy endings (even with bittersweet overtones), the foal comes up after her, in those few minutes having sprouted (through willpower alone) wings large enough to carry him.]]
* Creator/AnneMcCaffrey's ''Literature/TowerAndTheHive'' series follows a large clan of Talents with PsychicPowers over numerous generations. It's indicated in ''Damia's Children'' that more powerful Talents usually but not always have more powerful children. Sometimes a powerful and a 'weak' talent can produce some truly remarkable results.
* In the ''Literature/YoungWizards'' series, wizardry is known to run in families, though it probably has more to do with inherited traits The Powers think make a good wizard more than any "wizardry gene" since the power has to be offered by them and accepted through the Wizards Oath. In Nita's family there's Dariane, her aunt and offscreen, her great-grandmother, all on her father's side.
* Both the ability to manifest Literature/{{Deryni}} powers and the Haldane potential (apparently a variant) are transmitted genetically; the trait is dominant, so only one parent needs to have the trait for an offspring to inherit it. Thus, so-called "half-breeds" are just as powerful as full-blooded Deryni. Deryni generally need to be taught to use their powers; carriers of the Haldane potential need no training, but must have the potential triggered by a outside action. This is usually done in a ritual, the specifics of which vary slightly from one generation to the next; certain heirloom objects are used, and new ones may be added.
* In the Franchise/StarWarsExpandedUniverse, Force Sensitivity is clearly heritable.
** It's kind of annoying how each new child of the Skywalker line is touted as having the Strongest Potential Ever. In ''[[Literature/JediAcademyTrilogy I, Jedi]]'' Corran learns that the creation of illusions and permutations of the JediMindTrick, ability to absorb and convert or channel energy, and the inability to use telekinesis unless currently channeling energy are all Halcyon family traits, and his grandfather was a Halcyon. Over time he manifests each trait. Jedi who are not Skywalker-descended can have non-Jedi siblings and relatives whose weak Force-Sensitivity manifests as things such as a bit of "luck" and accurate hunches.
** It seems like that if a Force-Sensitive is cloned, the clones will themselves be Force-Sensitive, as shown with [[Literature/OutboundFlight Jorus C'baoth]] and [[Literature/TheThrawnTrilogy Joruus C'baoth]]. Though the clone's origins are mysterious enough that it is entirely possible Palpatine created and discarded dozens of C'baoth clones before getting one with the original's power. The clone also makes a [[EvilKnockoff clone of Luke]], but the Luuke clone might not have been a Force user.
** When Vader clones [[VideoGame/TheForceUnleashed Starkiller]], the clone retains the original's extremely strong abilities (the original could pull a Star Destroyer from the sky, while the clone can disintegrate anyone around him with a Force wave and super-charge a ship turret to blow up a Star Destroyer). Additionally, Vader's attempts resulted in dozens of failed clones who still exhibit powerful abilities.
** One of the drawbacks of cloning Force Users though (therefore why neither the Jedi nor the Sith do so to shore up their numbers) is that cloned Force Users tend to be mentally unstable.
* Several of the creators of the Literature/OldKingdom invested their power in specific bloodlines. As such, the Abhorsens, royals, and Clayr all tend to manifest the appropriate powers as needed.
* In ''Literature/TheDresdenFiles'', magic runs in families, usually matrilinearly. This is part of a villain's plot in [[spoiler:''White Night'', when some of the White Court start killing off female magical practitioners too weak for the White Council to notice, on the logic that this will interfere with future generations of wizards and they can afford to wait.]]
* Well-known and a bit of a plot point in ''Literature/CodexAlera'', where powerful [[ElementalPowers furycrafting]] abilities tend to run in families. Centuries worth of selective marriage among the nobility have led to the High Lords all being ''[[PersonOfMassDestruction insanely]]'' dangerous, and [[AuthorityEqualsAsskicking the First Lord even more so]].
** Complicated by the fact that sufficiently skilled crafters can pass control of their pokemon on or before death, giving multiple meanings to "inherit their power".
* In ''Literature/TheElvenbane'', powerful elvish spellcasters produce children who are powerful, weak casters produce weak children, and intermarriage between strong and weak produces a child of intermediate power. At least in the first book, it's never explained where powerful spellcasters came from in the first place, but their attempts to stay powerful through the generations have led to severe inbreeding. Human spellcasting is also inherited, but in defiance of the trope it's an indirect and imprecise pattern. [[note]](Elves and humans aren't even from the same world, so the implication is that human magical power is determined through standard genetics, with multiple genes influencing power levels, and elvish magical power is determined through something else entirely. Then again, elves and humans can [[HalfHumanHybrid interbreed]], which shouldn't be possible for two species with very different genes. Then again again, it's a fantasy story--what do you expect?)[[/note]]
** Lampshaded in a narrative comment on how the elves don't really understand human inheritance or fertility.
** Lashana, the title Elvenbane, plays this relatively straight. She was sired by one of the magically powerful elvenlords upon a human concubine whose SlaveCollar was revealed to be [[RestrainingBolt containing]] tremendous PsychicPowers. Due to the synergistic effects elven and human magics have when wielded by the same individual, Shana's raw ability is... formidable.
* In ''Literature/{{Twilight}}'', Edward can read minds and Bella [[spoiler:can create sort of psychic shields]]. Renesme got the exact opposite powers. She can project her thoughts into other people's minds and [[spoiler:ignore psychic shields]].
* In John Twelve Hawks' (a pseudonym) book ''[[Literature/TheFourthRealm The Traveler]]'', the eponymous characters pass down their abilities genetically.
* All of Harry Keogh's sons in the ''Literature/{{Necroscope}}'' series gain his talents in speaking with the dead, and have the capacity to learn how to use math-based teleport skills. It's implied Harry himself inherited at least his "Deadspeak" from his own mother. The DistantFinale of the series implies that all Espers eventually pass their abilities on to their descendants.
* In the Literature/ChroniclesOfTheKencyrath series by P. C. Hodgell, the Highborn of the Kencyr can at times be so psionic that their powers blur the boundaries of reality. It's strongly hinted that their abilities are due to genes implanted from the even more powerful Arren-Ken, which occasionally manifest as felinoid body parts such as claws.
* Important matter throughout the ''Literature/KronikiDrugiegoKregu'' series. No one knows why only boys are born with magic, or why some mages are insanely powerful, but others seem to have no talent at all. The ruling magical class (whose ancestors are said to have conquered their land with a sword and magic) is desperate to find out, because they are slowly dying out and their SuperBreedingProgram doesn’t give any results. There are hints it may be connected with a recessive, sex linked gene (that’s why magic seems to be passed on from the mother’s side and why [[spoiler: there are so few female mages).]] Later the heroes discover [[spoiler: that citizens of a neighbor country (descendants of the original inhabitants) also have potential for magic,]] which goes against already established beliefs. [[spoiler: In the end it turns out that the native inhabitants of the continent always carried magical genes and the invaders’ blood was only a catalyst that let this potential truly manifest. That’a why most people of MixedAncestry are so powerful.]]
* In the ''Literature/{{Mistborn}}'' setting, genetics plays a direct part in whether or not someone is born with Allomantic or Feruchemical powers. As a result, the [[EvilOverlord Lord Ruler]] set up a deliberate program and laws to control the superhuman genetics, with only nobles being allowed to have Allomancy, and killing any of the "skaa" commoners who possess these powers (and going so far as to mandate the execution of any skaa woman whom a nobleman sleeps with) as well as genociding anyone with Feruchemy.
* In ''Literature/TheWheelOfTime'' series, [[MagicByAnyOtherName channeling]] comes in two stripes: some have the ability, and can learn to use it, and a very few have the spark, and will use it [[PubertySuperpower at a certain age]] whether they mean to or not. The implication is that the spark is a recessive trait, and this is supported by its being more common in isolated populations, and the fact that it is becoming rarer in men, who have been culled of the ability for millennia.
* In the Franchise/StarTrekNovelVerse, as of ''[[Literature/StarTrekTheFall The Fall]]'', Benjamin Sisko is watching his daughter Rebecca very closely, ever alert for any possible sign that she's inherited powers or abilities from the wormhole aliens, due to Sisko himself being "part Prophet". The idea that she might have [[GiveHimANormalLife is disturbing to Sisko]], to say the least.
* ''Literature/JourneyToChaos'':
** The Bladi Clan is made of humans with BloodMagic. That is, blood magic that is literally in their blood.
** The royal family of Ataidar has their RoyaltySuperPower passing their bloodline.
** Elves pass their Seed of Chaos parent to child. In this way, the seed mutates them in the womb.
* In ''Literature/ShamanBlues'', [[spoiler:Wiktoria]] inherits her father's magical abilities, despite the fact that magic genes are recessive. Justified by the mother also having some supernatural in her blood.
* For the most part, Wizards in ''Literature/DiscWorld'' are created from the eighth son of an eighth son. However, every ''son'' of a Wizard is also a Wizard, and the eighth son of a Wizard is a ''Sourcerer''. Wizards are forbidden to marry because of this.
* In ''Literature/SuperPowereds'', children of Supers tend to be Supers themselves. There are cased of [[MuggleBornOfMages kids of Supers being normal humans]] or kids of Supers being born [[PowerIncontinence Powered]]. In some cases, children's abilities can be similar to their parents', although it's demonstrated multiple times that no two powers are exactly alike. Siblings also tend to have generally similar abilities. For example, the twins Will and Jill Murray are a GadgeteerGenius and a {{Technopath}}, respectively. Also, Angela and Shane Desoto have manifestation abilities (Angela can manifest and control objects made of HardLight, while Shane can do something similar to shadow-based constructs). In addition, both the Desoto siblings have inherited their grandfather's abilities, although he can control both light and shadow ([[spoiler:he's also the first costumed Hero, Captain Starlight]]). Chad Taylor's ability is nearly identical to his father's, and he even manages to replicate some of his father's tricks. On the other hand, Alice's flight ([[spoiler:or GravityMaster]]) ability doesn't appear to have any relation to her father's [[AlchemyIsMagic transmutation]] or her mother's [[spoiler:[[{{Seers}} precognition]]]]. She was also born a Powered, not becoming a Super until a special procedure is invented to give a Powered control over his or her ability. It's eventually revealed that [[spoiler:her primary ability is very similar to that of one of her uncles', who also happens to be a professor at her university]]. Hershel/Roy's ability is remotely similar to their father's, although not for reasons they initially think ([[spoiler:they initially assume that, since Titan is a strongman, then this is why Roy has SuperStrength; however, Titan's true power is adaptation, and so is Hershel's, except, in the latter case, he manifests Roy as his stronger alter-ego. Roy's maximum strength is proportional to Hershel's, so Hershal actually has to work out in order for Roy to get stronger past a certain point]].
* In ''Literature/The39Clues'', the Cahills have a downplayed version. Each branch of the family has a different special quality (Lucians are leaders and schemers, Ekatrina are genius scientists, Tomas are gifted athletes, and Janus are great artists) due to their ancestors (siblings Luke, Katherine, Thomas, and Jane Cahill) each taking one-fourth of a serum (meant to cure the bubonic plague) which gives the imbiber all of those qualities. [[spoiler: The fifth branch, the Madrigals, don't have any genetic special quality, since their ancestor Madeline Cahill was born after the serum's creator had died. They've still managed to produce [[TheUnchosenOne such luminaries]] as Deng Xiopeng, William Shakespeare, and the protagonists, Amy and Dan Cahill.]]
* Generally averted in ''Literature/VillainsCode'', where children of metahumans aren't necessarily going to become metas themselves. For example, Ivan's kids appear to be perfectly normal kids ([[spoiler:then he finds out that his daughter has recently become a meta, although it's implied it has nothing to do with genetics]]). Helen's daughter hasn't inherited her (or any) ability, which makes sense, since Helen's ability isn't genetic. This trope ''might'' play straight with Beverly, whose father was able to get a magical artifact working, just like Beverly herself (although a different artifact). It's implied that their family has a latent ability to manipulate magic.
* Invoked by the Bene Geserrit in ''Literature/{{Dune}}'', whose breeding program aims to produce the Kwisatz Haderach, a person with prescience. As it turns out in the sequels, this is GoneHorriblyRight, as said Kwisatz Haderach turns against them.
* Zig-zagged in ''Literature/TheFifthSeason'' with the FunctionalMagic of orogeny. People are born with the "curse" and it is heritable to an extent, which the Fulcrum encourages by enslaving every "feral" orogene and [[SuperBreedingProgram forcing powerful orogenes to have children together]]. However, orogenes can also be born to {{Muggle|s}} families and non-orogenes can be born to orogene parents, an uncontrollable element of [[RandomlyGifted randomness]] that infuriates the Fulcrum.

[[folder:Live Action TV]]
* ''Franchise/BuffyVerse'', the Master's bloodline, unique in origin among vampires has produced a number of particularly powerful and horrible Vamps, chief among those were the Whirlwind: a group of four most recurring vampire adversaries in both series consisted of Darla, Angelus, Drusilla and Spike. Each and every one of them can fight on par with the Slayer and had come close of killing her more times than most.
* ''Series/{{Heroes}}'' goes with the second of the four options; the children of heroes are almost certain to have powers of their own, but the child's powers are rarely related in any way to the parents'.
** While Matt seems to have the same powers as his father; Nikki, with super strength, and DL, with phasing powers, somehow manage to have a kid who can talk to machines. The latter example is ridiculous, as the entire premise of Heroes revolves around [[HollywoodEvolution human evolution]]. Someone should tell them that this isn't how natural selection works.
** The whole reason Micah (the aforementioned technopath) even exists is that [[spoiler:Linderman arranged for Niki and DL to meet, marry, and have children, so that he could then use Micah to (in a roundabout way) seat Nathan in the Oval Office.]]
** Nathan [[spoiler: is the exception to this rule. He's the only one in the family who wasn't born with powers and instead got them from a SuperSerum. He manages to keep both this and the fact he has a power at all a secret from many characters, eventually leading to him having some sort of Hitler-esque FantasticRacism against people with abilities. He gets over it.]]
** Similar to Micah, Hiro's power (space/time manipulation) has nothing to do with his father's power (probability calculation) or his mother's power (HealingHands). Ditto for Claire (HealingFactor), whose father can fly, and whose mother can produce fire. Incidentally, though, her mother's power is nearly identical to her mother's brother's power.
* ''Series/{{Medium}}'' has variant 1, as all three of Allison Dubois' daughters inherited psychic powers. Her half brother also has them, which raises as yet unanswered questions about whether any of their parents were psychic too.
* Happens in ''Franchise/StarTrek'', most notably with HalfHumanHybrid individuals whose alien parents come from races with special abilities.
** Although [[Series/StarTrekTheOriginalSeries Spock]] is half-Vulcan/half-human, it seems that Vulcan traits are extremely dominant, as it is constantly emphasized how his Vulcan physiology differs from humans. He possesses Vulcan anatomy, as well as their telepathic powers. In fact, the only time the physical aspect of his human ancestry comes up is in regards to his viability as a blood donor for his father.
** [[Series/StarTrekTheNextGeneration Deanna Troi]] is half-Betazoid/half-human. Betazoids are physically closer to humans than Vulcans are, but possess extensive empathic and telepathic abilities. Deanna seems to have inherited a watered-down version of these, being mainly empathic, but able to communicate telepathically with other telepaths. It comes up on the show that most Betazoid descendants with three-quarters human ancestry do not generally exhibit any psionic ability.
** In one very peculiar instance of non-genetic superpower inheritance depicted in the episode ''True Q'', a young, seemingly human, woman born to two parents who were secretly members of the Q Continuum is herself a Q, complete with functional omnipotence that she is unaware of. To all available tests she seems to be human. But Q causes her to invoke her powers by triggering a warp core breach while she is in Engineering, leading her to instinctively use her powers to stop it. She subsequently uses her Q powers very easily.
*** Q are extradimensional EnergyBeings. The ones that look human are using AFormYouAreComfortableWith. It's hinted that Amanda's parents suppressed her powers (Q can supress the powers of other Q) and made her believe she was human. She had the powers all along, she just didn't realize it.
* In ''Series/StargateSG1'', some humans inherit [[{{Precursors}} Ancient]] genes, though the only "super power" they provide is the ability to be recognized as a valid user by Ancient technology.
** Not really. In ''Series/StargateAtlantis'' it is said that many tech that requires the ATA gene can be controlled mentally by those who have the gene. Sheppard himself says about the puddlejumper that "a lot of fighter pilots would kill to fly this thing; it's like it reads your mind..." Cue the jumper displaying a sensor readout on the windshield and dispensing a life sign detector when he wonders about how they should find their target. Sheppard then mentions he's [[RetroactiveWish thinking about a nice turkey sandwich]]. "Worth a try."
** Also the ATA gene is completely artificial; it was created by the Ancients for the express purpose of having a genetic marker they knew would be unique to their species.
** Teyla has inherited some Wraith genes from her father, who was experimented on by a Wraith scientist. As a result, she can jack into the Wraith psychic network and even temporarily take control of Wraith (while also leaving her own body exposed to be controlled by a Wraith).
* ''Series/ThatsSoRaven'' has PsychicPowers that skip a generation, making them most likely recessive.
* On ''Series/PainkillerJane'' this is apparently the reason for the [[DifferentlyPoweredIndividual neuros]]' abilities, though the agency frankly admits they're not sure of the real cause. Jane is specifically stated ''not'' to be a neuro as well, so it's anyone's guess where she got ''her'' [[HealingFactor ability]]. It's implied she was injected with something just prior to being thrown out of a [[DestinationDefenestration high-rise window]]. [[spoiler:It's eventually revealed to be all a part of an experiment by the same corporation to create immortals. All the neuros they've been fighting are actually first-generation failures. Jane and the Chameleon represent the more successful second generation. As a bonus, they can't be chipped.]]
* In ''Series/The4400'', children of 4400s do not develop abilities unless one of their parents carries a unique mutation caused by a particular malfunctioning radiotherapy machine. The only offspring we see with abilities is Isabelle, who displays AllYourPowersCombined, despite being the child of an empath and a telekinetic.
* ''Series/TheThundermans'': Anyone who was born to superheroes or supervillains have superpowers that are varied and do not necessarily have to do with their parents' powers.
* ''Series/BlackLightning'' gives us Jefferson Pierce, whose powers turn out to be the result of [[spoiler:a vaccine he took as a child as part of a secret government agency's attempt at pacifying the black communities]]. However, the change was genetic in nature, which means his daughters end up developing powers as well. However, only his youngest Jennifer develops similar electric powers (not quite identical, though), while her sister Anissa has SuperStrength.

[[folder:Tabletop Games]]
* ''TabletopGame/{{Warhammer 40000}}'''s [[SuperSoldier Space Marines]] are the genetic children of the superhuman Primarchs, inheriting their comprehensively superhuman biology... and [[GeneticMemory a few other things]].
** They are not "children" of the primarchs in a true sense. They are born normal but then become Space Marines only through a regime of mental, physical and spiritual conditioning that includes the addition of, [[BioAugmentation artificial biological implants]] (extra heart, growth hormone generators, venom glands etc.) it is these implants that have their own genetic lineage, tracing back to the Primarchs. Because of the hypnotic and mental conditioning, it is also possible that they do not have "genetic memory" but have certain memories implanted (such as Sanguinius' death for the Blood Angels).
*** One of the implants is the gene-seed, containing "mental, physical, spiritual, martial, and fraternal characteristics" and being collected from any casualty so it can be used to create a new batch of artificial organs. It is said to contain genetic memory, which is why they wait until death to collect it.
** The Primarchs themselves were created by the Emperor using his own genetic material. They were practically demigods far beyond mere humans as a result. Each Primarch also embodied one aspect of the Emperor. The exception was [[TheAce Sanguinius]], who supposedly embodied ''everything'' about the Emperor.
* Genestealers are a weird one. Their genetics are predictable in how a bloodline works and the abilities that are passed down, though the immediate generation after the first don't get any powers. Initially you have a genestealer infect its target. This new host becomes part of the group mind of the genestealers and becomes compelled to mate. The host looks normal, but the offspring will be bald and have slight bit of carapace and more than human speed and strength. This offspring later mates with other half-breeds to produce a full-blooded genestealer complete with 4 razor sharp claws and the ability to infect new hosts like its genestealer grandparent.
* ''TabletopGame/{{WarhammerFantasy}}'', if you have a chaos-tainted parent then there's a good chance you'll be a disgusting mutant too. One reason why the Old World has so many Beastmen is that some of the mutant offspring who were left to die from exposure, were found by Beastmen and could breed true.
* ''TabletopGame/{{Exalted}}'''s Dragon-Blooded work this way. For any given child of a dragon-blood, case 4 or 5 will be in effect. There's about a 60% chance of a child of two dragon-blooded parents Exalting, and that decreases if one of the parents is mortal.
** Similarly, the children of the celestial exalted also inherit diminished forms of the powers of their parents and can (in rare cases) pass those on to their own children.
* The whole point of the Slivers from ''TabletopGame/MagicTheGathering'', with an additional step. They eat things, then assimilate the genes, then have kids, and their kids have the prey animal's advantages. Oh, and those advantages can be shared with any other Sliver in the area.
* In both ''TabletopGame/WerewolfTheApocalypse'' and ''TabletopGame/WerewolfTheForsaken'' games, being a werewolf is a hereditary thing, but that doesn't necessarily mean all children of werewolves will Change. The coupling between a Changed werewolf and the unchanged child of a werewolf (known as either Kinfolk or Wolf-Blooded, depending on the game line) has a greater chance of producing a werewolf; relations between two werewolves [[FetusTerrible typically leads to bad things]]. First-generation children of werewolves typically have the greater chance of undergoing the First Change, but those further down the family tree may suddenly undergo the Change themselves.
** In the 20th Anniversary edition of TabletopGame/WerewolfTheApocalypse we are told that the only ones that really understood the rules of shapechanger genetics were the Were-Aurochs, who could guarantee that a paring they arranged would produce changer children. Unfortunately the Werewolves killed them all several thousand years ago. Oops.

[[folder:Video Games]]
* ''VideoGame/{{Pokemon}}'' has types 1 and 3. Baby Pokemon can inherit any move both their parents know, that they could get by LevelGrinding. They can also inherit [[PowersAsPrograms TM or HM]] moves, or certain moves that can only come from breeding, from their fathers. Thus, it's possible to have a level 1 baby slinging FrickinLaserBeams around.
** Further, you can increase the chances that an offspring inherits its mother's Nature by giving her an [[PowerLimiter Everstone]].
** They can also inherit up to 3 [=IV=]s (Individual Values, the genes' equivalent in Pokémon) from their parents, the other [=IV=]s being set by Random Number Generator. In 4th Gen, equipping a parent with a Power item allow the child to inherit the IV linked to the Power item (example: equipping a Power Bracer on a parent will make the child inherit the Attack IV of this parent).
* ''VideoGame/{{Touhou}}'s'' Reimu Hakurei benefits from this so much it's not even funny. As a Hakurei, she gets superpowers related to boundaries and [[BarrierWarrior barriers]] that was given to her bloodline to maintain the Great Hakurei Barrier. It's thanks to this that HardWorkHardlyWorks, while TheRival Marisa has to go a relative CharlesAtlasSuperpower route to catch up.
** There's also her [[TheRival rival]] {{miko}}, (well, other rival, at least,) Sanae Kochiya, who is actually blood-related to the Goddess that she serves, and as such has innate divine magic.
* ''Franchise/AceAttorney'':
** Though not superheroes, Apollo and Trucy benefit from this. [[spoiler: They both inherited this ability from their grandfather and mother.]] Interestingly, Apollo seems to be the only one who uses the power for anything more than poker.
** The ability to channel spirits runs in the Fey bloodline...sometimes. Despite being born first Morgan Fey had no powers and was reduced to being part of the branch family, in service to the main family of her younger sister Misty. This understandably caused her a bit of stress. It must be recessive or something, as her daughter Pearl ''does'' have channeling powers.
* The ''Franchise/DragonAge'' games imply that magical ability is transmitted genetically; Leandra Amell of ''VideoGame/DragonAgeII'' remarks that magic has always run in her family, and considering that her husband was a mage it's unsurprising she has at least one mage child. She's related to the family of the human mage PC from the first game, who had several mage siblings...all of whom were taken from their family by the Templars, one after the other.
* ''[[Videogame/FirstEncounterAssaultRecon FEAR]]'' zig-zags this trope. While genetics are apparently at least some factor in [[PsychicPowers psychic ability]], the fetus must also gestate in the womb of a powerful psychic mother to reach its full potential. This is how [[spoiler: the Point Man]] and [[spoiler: Fettel]] were so powerful.
* ''Franchise/{{Metroid}}'': Part of what makes Samus Aran such a high achiever is the Chozo blood she was infused with as a young child. And, thanks to ''VideoGame/MetroidFusion'', she also has the [=DNA=] of a metroid. You know, those monsters that are pretty much invincible to all but ice. And classified as [=WMDs=].
* The Paralogue children from ''VideoGame/FireEmblemAwakening'' inherit their parents skills via LamarckWasRight. Players often have certain characters paired up or have them change classes before the paralogue stage so their kids have inherited devastating abilities and very high stats they normally wouldn't get in their starting class or gender (such as giving male characters Galeforce). Speaking of which, most the kids (with a few exceptions) are also in the same starting / Base classes as their mothers...
** If Nah and Yarne are any indication - [[OurDragonsAreDifferent Manakete]] and [[HairRaisingHare Taguel]] ShapeShifter abilities are directly genetic too.
* In ''Videogame/MortalKombat9'', it is revealed that Johnny Cage is descended from superhuman Mediterranean warriors, resulting in his energy blasts. His daughter [[Videogame/MortalKombatX Cassie]] continues the bloodline. Interestingly though, in this timeline the only canonical time those powers have ever been used is [[spoiler: protecting someone else from Shinnok]]. Everything else was [[CharlesAtlasSuperpower just martial arts and Special Forces training.]]
* In ''Videogame/{{Tekken}}'', the maternal part of the Mishima bloodline gives Kazuya and Jin their Devil gene abilities. From Heihachi Mishima, every one of his descendants get at least a measure of his superhuman strength and endurance, including his half-Swedish son Lars.
* Deconstructed in ''Videogame/{{Blazblue}}''. The Yayoi family, one of the ruling families of the [[OneWorldGovernment NOL]], is focused on being the house with the best [[{{Magitek}} Ars Magus]] users. They would only have children with strong Ars Magus users, and when those became hard to come by the family started inbreeding. The house is still magically strong but it's a lot smaller and less powerful than it used to be, as genetic defects crippled the family bloodline. The current heir, Tsubaki, is quite powerful but [[RoyallyScrewedUp a bit unstable sometimes]] and uses a weapon which will blind and eventually kill her. To add insult to injury, her best friend [[AlwaysSomeoneBetter Noel]] is even more powerful despite her relatively low family [[spoiler:(due to being a [[RobotGirl Murakumo]])]], which is just another entry on the laundry list of things Tsubaki [[GreenEyedMonster is envious of]].
* Yunobo in ''VideoGame/TheLegendOfZeldaBreathOfTheWild'' inherited his BeehiveBarrier powers from his ancestor Daruk.

* This is lampshaded, like everything else, in ''WebAnimation/GirlchanInParadise''. Ken-Star is referred to repeatedly as having "thaaaaaaaaaat bloodline", but we never see what it does.
* Mostly {{averted}} in ''WebAnimation/{{RWBY}}''; as [[SoulPower Semblances]] are manifestations of a person's Aura and each person is unique in that sense, there's little chance that a parent will have the same Semblance as their children, assuming either generation even unlocked their Semblance.
** The [[BlueBlood Schnee]] family is distinctly noted as an exception with their [[InstantRunes glyphs]] being hereditary. Weiss' father, who married into the family (but [[BerserkButton don't remind him of that]]), does not have that Semblance.
** Though not a Semblance, [[spoiler:Ruby's Silver Eyed Warrior abilities]] were inherited from her mother.

[[folder:Web Comics]]
* ''Webcomic/GirlGenius'' uses genetics to pass down the "Spark" -- a superhuman talent for and obsession with a particular branch of science or technology. Although as yet there's not that much data to go on, the Spark appears to have greater strength in successive generations, especially when combined across multiple ancestral lines. The greater your spark, the crazier you are. Maybe the inbreeding helps a little with the craziness, too.
* In ''Webcomic/EvilInc''., Captain Heroic and Miss Match's son, Oscar, appears to be an example of Option 5 (Though he's only five, that so that could change). He uses a suit of PoweredArmor provided by his grandfather, Commander Heroic, to keep up with his peer group.
* ''Webcomic/EverydayHeroes''
** The original Mr. Mighty was the grandfather of the current Mr. Mighty. His wife is a normal human; one child is a mix of Options 1 and 2 (her Dad's powers, plus shoots force beams from her eyes), the other is Option 5 (no powers).
** Also, Dot Dash's son appears to be Option 5 as well.
* In ''Webcomic/{{Juathuur}}'', affinity to shift, shadow and shard magic is inheritable. People of other bloodlines can learn a few tricks, and that's it.
* The three sons of Luk River from ''Webcomic/IrregularElis'' have powers like his father.
* Averted with [[spoiler: the Kids and Trolls]] in ''Webcomic/{{Homestuck}}''. Despite having god like powers, there's no indication their parents ever had anything abnormal about them, beyond being [[BadassNormal really badass]]. [[spoiler: They aren't genetically related to humanity (or trollanity) anyways, so it's possible that either their parents carried recessive genes for their powers or Sburb itself empowered them in some way]].
* Seems to be a recurring theme in some of Tiffany Ross's [=GNIPs=]:
** In ''Webcomic/TheCyantianChronicles'' "Elites" had ancestors who were genetically modified by a conquering alien race as [[BloodSport pit fighters]], as such they have a HealingFactor, SuperStrength, extended life-spans, and other powers depending on their species. The traits sometimes skip a generation though, it appears to be recessive.
*** More recently are some of Exotica Genoworks' militia products, most notably the [[PsychicPowers Siracs]].
** Lexx of ''Webcomic/AlienDice'' is supposedly part of a bloodline of "enhanced" [[HumanSubspecies Rishan]], as such the Alien Dice Corporation is desperate to keep ahold of him and any relatives they can find. On one occasion they offer him freedom in exchange for sperm samples.
** The currently on hiatus comic [[http://shivae.net/pure/ PURE]] portrays a [[TheSocialDarwinist socially Darwinistic]] city-state where people without superpowers of some kind [[WhatMeasureIsANonSuper are euthanized at the age of 18]] to keep them from contaminating the gene pool. Members of the de facto royal family tend to share powerful telekinetic, telepathic, and teleportation abilities.
* In ''Webcomic/AMadTeaParty'', Connie and Matilda, the two main characters, have inherited some but not all of their parents' genetically enhanced abilities.
* In ''Webcomic/ElGoonishShive'', aptitude for magic is inheritable and if one's lineage contained lots of powerful magic users one would be more likely to be able to gain access to powerful magic, with the child of two wizards guaranteed to also be a wizard. [[spoiler: It would later be revealed that all wizards and people with inherited affinities are descended from Immortals through the Immortal-Human hybrids known as Elves]].
** Tedd turned out to be something of an anomaly, not only does he not inherit any magical ability from his mother's lineage, he [[MuggleBornOfMages lacks even the baseline-human natural resistance to magic and spell craft]]. This has driven him to use his great intellect to develop {{Magitek}} for himself and other non-mages to be able to enjoy all the fun and useful aspects of magic. [[spoiler:It later turns out that Tedd is a {{Seer}}, a rare type of wizard that differs from the norm. One particular way is that they have high magic resistance, and that resulted in a false negative that led to Tedd being falsely diagnosed as magically-impaired when it turns out he's actually the exact opposite]].
* PlayedWith in ''Webcomic/KongTower,'' with half-siblings Aya and Steve, who's father is a RealityWarper who works on ToonPhysics. Aya's mother is a {{Samurai}} with Shinto based magic powers, but Aya's "abilities" are essentially a more limited version of her father's, in the form of being {{Animesque}}. Steve's mother on the other hand is a psychic, giving Steve… MediumAwareness, which most people in-universe interpret as low level psychic and RealityWarping powers combined with being a functioning schizophrenic. Reference is also made to Superheroes who lack certain RequiredSecondaryPowers dating others who have versions of the abilities they're missing in the hopes that their offspring would be more functional, but whether this would actually work has yet to be shown.

[[folder:Web Original]]
* The ''Roleplay/GlobalGuardiansPBEMUniverse'' is an "unlimited source" setting, where superpowers can be gained through any possible way that can be imagined. Nevertheless, and regardless of what real-world genetic science says, its guaranteed that the child of two superhumans will have either the same powers as one of their parents, or a mix between the two. (Children with only one superhuman parent tend to have a 50/50 chance of getting either the same powers as their parents, or else no powers at all.) People who get their powers from technology don't count.
* In the Literature/WhateleyUniverse, all of the above (well, really all but #3). {{Mutants}} are people who have manifested (usually around age 14) powers based on a 'meta-gene complex' in their DNA. For unknown reasons (since no one understands why some people with this complex become mutants and others do not), children of mutants are much more likely to also become mutants. At the Whateley Academy (a [[SuperheroSchool high school for mutant kids]] set in scenic Dunwich New Hampshire), there are currently kids who have powers utterly unrelated to their parents' powers. But there is one girl who looks just like her mother used to, and has an exact copy of her mother's powers, right down to the ability to manifest something that looks like a big ol' flaming sword. There are also two students who are the kids of one of the world's most notorious supervillains, and they have his trademark forelock horns (along with his unattractive facial features), but different powers.
* ''Literature/{{Worm}}'' falls somewhere between options 3 and 5. Children of parahumans don't inherit any powers when they're born, but they seem to be far more likely to have the potential to have a [[TraumaticSuperpowerAwakening trigger event]] than normal, and the trigger can be far less traumatic. If they do get powers, they're almost always variants on their parents', as described in 3. At the time of the story, the third generation capes are just starting to appear. Oddly, this doesn't appear to be to do with genetics, since adopted children also sometimes experience the effect. [[spoiler: It's because the [[HeroicHost parahumans']] passengers are seeking to reproduce, and a child spending a lot of time near a parahuman (and their passenger) lets the passenger copy itself over to the child.]]
** Naturally, some groups (notably Heartbreaker and the Fallen) have decided this is a good way to get more capes on their sides.

[[folder:Western Animation]]
* In ''WesternAnimation/AvatarTheLastAirbender'', every descendant of the Fire Nation royal family is an extremely powerful bender or will be one. Bending is stated to generally run in family lines, but there are also plenty of examples of benders whose parents never had the ability and children born of benders who don't inherit it.
** In ''WesternAnimation/TheLegendOfKorra'', Aang (Avatar/Air Nomad) and Katara (Waterbender) have three kids: Kya (Waterbender), Bumi (Non-Bender [[spoiler:who gains airbending from Harmonic Convergence later]]), and Tenzin (Airbender). Tenzin and his wife, Pema (Non-bender), have 4 children. All of them but the youngest are Airbenders, with the youngest being predicted to be another Airbender.
** To add to the confusion, there was also an episode with a pair of identical twins where one was an earth-bender and the other was just a {{Muggle}}.
** Advanced bending talents, such as metalbending, also appear to be genetic. Toph created the talent, but both of her daughters and three of her five grandchildren are also metalbenders, with the remaining two being a non-bender and [[spoiler:post-Convergence, an airbender]]; in-series, the probability of an earthbender having the knack for metalbending is one in a hundred, meaning that if it's ''not'' genetic [[BornLucky Toph could have made an absolute fortune betting on ostrich horse races]]. Meanwhile, exiled crime boss Yakone, even after Aang removes his bending, supposedly passes his gift for bloodbending at times other than the full moon to his children, [[spoiler:Tarrlok and Noatak/Amon]], but since he trains them it could just be his tutelage rather than an intrinsic talent. And ''nobody'' knows what's up with lavabending; apart from a few Avatars, only Ghazan and [[spoiler:Bolin]] use it, neither of them have any kids in the series, and whether [[spoiler:Bolin]] being half-Fire Nation was a factor is never brought up because Ghazan's pre-Red Lotus backstory is a mystery.
* In ''WesternAnimation/AmericanDragonJakeLong'', the gene that gives you dragon powers is apparently recessive as it skips a generation. This means Jake, his sister, and his grandpa all have dragon powers while his mother doesn't.
** The most probable explanation is that males [[http://en.wikipedia.org/wiki/Genomic_imprinting imprint the gene]] (turn it off before passing it along in a gamete). Jake and Haley were both lucky enough (25% chance of both inheriting it) to inherit the gene and since it came from their mother the gene was turned back on before being passed along.
* ''WesternAnimation/KimPossible'' plays this to a lesser extreme: the eponymous character's father was a rocket scientist, her mother was a brain surgeon, her grandmother was a kung-fuing underwater-demolitioning aviatrix, her brothers are practically miniature [[MadScientist mad scientists]], so Kim Possible would be a world-saving SheFu cheerleader.
-->'''Kim''': I guess my genetics rock.
* In the ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', WordOfGod that ponies of different types (earth ponies, unicorns, and pegasi) can interbreed. The season 2 episode "Baby Cakes" confirmed when earth ponies Mr. and Mrs. Cake have twins who are a pegasus and a unicorn, which Mr. Cake explains by saying that he has unicorn ancestry, and Mrs. Cake has pegasus ancestry. [[LampshadeHanging "That makes sense, right?"]]
