->''"All of the girls look exactly like Mommy and all of the boys look exactly like Daddy!'' [beat] ''This is not how biology works!"''
-->-- '''WebVideo/TheFanFictionCritic''', review of ''The Affair''

[[HotSkittyOnWailordAction Two-species couples]] open up a lot of questions about what [[ArtisticLicenseBiology their children]] will look like. This is avoided in many cases by having all boys look like their fathers and all girls look like their mothers. This can also apply to different types within the same species (e.g., in ''Lady and the Tramp'', the eponymous dogs are of different breeds. Female offspring look like their mother, the one male like his father).

In American media, female dogs are often represented by Poodles and, occasionally, other elegant-looking breeds like Malteses, Salukis, or Bichons; other breeds, and mutts, are usually male. [[FemaleFelineMaleMutt Also, almost all cats are female]].

It should be noted in male/female same-species examples given here that it ''is'' possible for traits to be sex-linked. Since human females have two X chromosomes and males have one X and one Y (usually; there are cases where it is not so clear), diseases or other things can be restricted to one sex. One example is colorblindness; about 5.8% of males, but less than 1% of females, are colorblind in some way or another (although it should be noted that males get their X chromosome from their mother, so whether one's father is colorblind has no influence on whether one is colorblind himself). (Cats actually ''have'' sex-linked coat patterns that are probably the closest thing to a real-life example, although coat patterns can occur in multiple breeds: almost all calico and tortoiseshell cats are female.) This can be even more true with some insect species that have fewer chromosomes to worry about. At least one species of ants actually has the genetic material of the two sexes completely separate.

SubTrope to EitherOrOffspring, which is about offspring of two-species couples only inheriting one species in general. SisterTrope to DominantSpeciesGenes, where one species dominates regardless of gender. Compare with BizarreSexualDimorphism, where a single species has very different-looking genders, and PatchworkKids, where the children look (and often act) like a perfect mix of the parents. (Of course, with TertiarySexualCharacteristics, it's quite reasonable that these ''would'' be--and are--passed on from same-sex parent to child...)

You can expect this trope even more when at least one of the parents is a member of a OneGenderRace, although it does make a pretty good excuse.

Compare JacobAndEsau.


* In the Burger King commercials, Advertising/TheBurgerKing has a human wife, a human daughter, and a son with a freakish plastic head like his own.
* The Whopper family, who consist of: Whopper, Mrs. Whopper (who is human), Whopper Jr. (which would make Whopper's full name "Whopper Whopper Sr."), Spicy Whopper, and a teenage girl (who is also human). God help that girl if they invent the Whopperette.
* Since the late '90s, Jack In The Box commercials have featured the eponymous "Jack" who has a ping pong ball head. In later commercials, his blonde normal-noggined wife Cricket was introduced. However their son Jack Jr. has the same gender-specific head defect as his father. Jack's own father was also shown to have the ping pong ball head. His (normal head-ed) mother even asks him: "Have I ever told you how difficult your birth was?" Similarly, Jack's brother (seen in prison once, and then at a family photo) has one of the large heads. To make matters the more confusing, "Grandma Box" gave them the long-pointed nose (as she has a normal head but a long nose). We also recently were introduced to his cousin from Philly who has the same ping-pong head with a mullet. He too has a normal human wife.
* The adverts for the Silentnight range of beds and mattresses feature a cartoon family consisting of a Hippo father and a Duck mother (who is much smaller than her husband) with a duck daughter and a (large) hippo son. [[HotSkittyOnWailordAction Just think about that for a while]] (or rather, don't).
* [[http://www.youtube.com/watch?v=cZrkp2La3FA In a Japanese commercial]] for the heavily advertised ''VideoGame/{{Solatorobo}}'' (a mecha game feature anthro characters), this trope is illustrated at first between an interspecies couple and then subverted when a hybrid is shown! Here’s to hoping [[HotSkittyOnWailordAction Cheetahs and Bulldogs]] never mate.

[[folder:Anime & Manga]]
* Inverted in an unusual case in ''Manga/{{Trigun}}'' with the Nebraska Family. It's unusual in that the two species in question are not animals, but human and giant: the human father and giantess mother have a normally-proportioned human daughter and several giant sons.
* In the ending of ''Manga/FullmetalAlchemist'', Ed's son retains the [[spoiler:Xerxesian]] racial traits of his father and grandfather, while his daughter is an ordinary Caucasian girl like [[VictoriousChildhoodFriend her mother]].
* The above picture is from a {{Hentai}} manga story, ''My Younger Sister Is a Scylla'', where a Scylla baby (human top half with octopus tentacles instead of legs) is adopted by a human fishermen family and marries her stepbrother once adult.
* This is sort-of the case of Hiei and Yukina in Manga/YuYuHakusho, as Yukina is an Koorime, like their mother, while Hiei is a fire demon, like his unseen father. However, the Koorime are an all-female species of ice demon that reproduce asexually, meaning Yukina doesn't actually have a father. It's suggested that any male who mates with a Koorime will result in a child of the father's species, which is why mating at all and the children that result are taboo.

[[folder:Comic Books]]
* Subtly utilized in ''ComicBook/UsagiYojimbo'' (all previous pairings being same-species), when Ino (a pig) and his wife (a... [[CartoonCreature round-eared animal]]) are later shown with their daughter, a round-eared animal like her mother. According to {{Word of God}}, it always works like that--women are always the same kind of animal as their mothers, and men as their fathers.
* This is the way Sonic and Sally's children are represented in all of the {{flashforward}}s in the ''ComicBook/ArchieComicsSonicTheHedgehog'' comic. The recent "30 Years Later" storyline shows this to also be true for Tails and Mina's children. This also applies to Bunnie and Antoine's children, though DependingOnTheArtist, the boy may have Bunnie's coloration and the girl Antoine's. Somehow, they [[LamarckWasRight both inherited robotic limbs from their mother]]. A notable exception is Jon, the son of Rob O'Hedge and Mari-An. Despite being male, he is an Echidna, like his mom.
** This would ultimately be justified in [[AllThereInTheManual "The Complete Sonic Comic Encyclopedia"]]: when Mobians of different species mate, normally, this results in twins, where each twin carries one parent's physical traits, but in rare cases such interspecies pairings produce a single child with physical traits of both. Little Jon O' the Hedge is presumably a retcon who would have turned out as a proper echidna/hedgehog hybrid when he grew up, much like the post-Super Genasis Wave character Princess Undina, who mostly resembles her anglerfish mother but lacks a light and has her father's purple coloration.
* Used in the third issue of the Spanish-for-a-French-market comic ''ComicBook/{{Blacksad}}''. The chief of police is characterized as a German Shepherd, his wife is some sort of spaniel. Their son is also a German Shepherd, and their daughter the same Spaniel breed as her mother.
* Averted in the underground comic of "Dino-Boy". He's a human with a dinosaur body (or a dinosaur with a human head) who married a human woman. Their kids are both half-dinosaurs--but the son has a human body and a dinosaur's head, while the daughter is like her father.
* Averted in ''Comicbook/{{Fables}}'' with Snow White and Bigby's kids; before they learn how to change shape, both boys and girls cover the spectrum from fully human-looking to human-wolf to fully wolf-looking, and one, well... takes after [[ElementalEmbodiment his grandfather]].

[[folder:Fan Works]]
* Played straight with [[WesternAnimation/{{Superjail}} the Warden and the Mistress]]'s twins Matilda and Ethan in ''[[http://www.fanfiction.net/s/8803490/1/Extended-Stay Extended Stay]]'' in that both of them look like miniature versions of their parents. They even wear the same clothes their parents have worn. Combined with StrongFamilyResemblance.
* Several ''Literature/HarryPotter'' fics involving Veela state that in a Veela/wizard pairing any girls born are full-blooded Veela while boys are human and, at most, carriers of the applicable gene.
* In ''Fanfic/TheBridge'' this is how mermare reproduction works. Mermares are a OneGenderRace, which necessitates mating with equines of other races. If the mermare's foal is female, she'll be a new mermare with different traits depending on her father's race. If the mermare's foal is male, he'll be the same species as his father and feel a connection to the sea.

[[folder:Films -- Animation]]
* Averted in the sequels to ''WesternAnimation/{{Balto}}'', where the eponymous wolf/dog hybrid's litter with his red-furred Husky LoveInterest Jenna all take after her, except for his youngest daughter Aleu, who looks even more like a wolf than he does. All of the red puppies look like Jenna in general but two of them look different from the others. One, Dingo, has a red stripe connecting to his nose and another unnamed puppy has a face that is entirely red except for their muzzle.
* At the end of ''Disney/LadyAndTheTramp'', three of their puppies look like pure-bred cockers like Lady, while the boy Scamp looks just as much a lovable mongrel as his father. They should ALL be mongrels to one degree or another. In the film sequel ''Disney/LadyAndTheTrampIIScampsAdventure'' the cockers are all female, but [[ComicStrip/{{Scamp}} the earlier newspaper strip]] [[AdaptationDisplacement on which it was partially based]] averts this by making one of the cockers a boy.
* In ''Disney/TreasurePlanet'', the children of [[spoiler:Delbert and Amelia]] display this. The three girls are clearly modeled after their mother and the boy is clearly modeled after his father. They aren't even the same species! [[WildMassGuessing Unless they are, and the species has that particular sexual dimorphism.]]
* Heavilly averted in ''WesternAnimation/Shrek2'' with Donkey and Dragon's offspring. You would expect this trope to be played, and then the children show up -- [[PatchworkKids winged fire-breathing donkeyish...]] [[UglyCute things]].
* The animated film ''WesternAnimation/RoverDangerfield'' appears to have the "breeds" version of this, Daisy (a collie) has a litter to Rover (a basset hound) and produces several apparently male basset hounds and one possibly female collie.
* In the 3rd sequel of ''WesternAnimation/OpenSeason'', married couple Elliot and Giselle end up with two baby does and one buck, with the does looking exactly like their mother (only difference being the color of noses - red and black), and their son the exact copy of his father.
* In ''WesternAnimation/SongOfTheSea'', Ben and Saoirse are both half-[[SelkiesAndWereSeals selkie]], half-human. However, Ben is identified as a human, like his father, and Saoirse is identified as a selkie, like her mother. [[spoiler: Saoirse [[BroughtDownToNormal becomes completely human]] at the end, though, since she had to give up her selkie powers in order to stay in the human world.]]

[[folder:Films -- Live-Action]]
* The Szalinski family in ''Film/HoneyIShrunkTheKids''. Amy has Diane's blonde hair, and Nick is a brunette who wears glasses just like Wayne is. Averted in ''Honey, I Blew Up the Kid'', where Adam resembles his mother.
* In ''Film/MomAndDadSaveTheWorld'', the planet Spengo has two humanoid sentient (?!) species, one of which resembles humans. The other consists of males that resemble bulldogs and females which resemble carp.

* In ''Literature/NorthernLights'', witches are an all-female species that mate with human males. Female offspring are witches, male offspring are human.
* ''Literature/CodexAlera'':
** [[PlayingWithATrope Of a sort]]: though background Marat characters are of both genders, all named characters of any tribe are the same gender. All named members of Gargant, Wolf and Herdbane tribe are male, all named members of Horse tribe are female. There are no named members of Fox tribe, which was killed in its entirety before the start of the series, but the only Fox character discussed and described was female.
** In the same series, it was remarked in one of the earlier novels that no one had ever seen a female Cane (giant wolf person), leading to rumors that there just weren't any.
* In Piers Anthony's ''Literature/{{Xanth}}'' novels, fauns and nymphs are males and females of the same species. It's also stated that 'daughters take after their mothers and sons after their fathers.' Dawn (a human) and Picka Bone (a skeleton) have a son and daughter, Piton and Data, with Piton normally a skeleton like his father while Data is human like her mother (though they can take either form, being crossbreeds).
* In ''Literature/TheHeroesOfOlympus'' satyrs and nymphs can reproduce. Male children are satyrs and female children are nymphs. Since we never see female satyrs or male nymphs anywhere in Rick Riordan's Camp Half Blood universe, this might be a case of OneGenderRace.

[[folder:Live-Action TV]]
* This concept is parodied and then subverted in ''Series/{{Scrubs}}'' when the AlmightyJanitor fantasizes about being married to Elliot. They are surrounded by little girls dressed as doctors like Elliot and little boys dressed as janitors like The Janitor. Elliot wonders if they're "pigeonholing the children," and The Janitor points out that it doesn't matter because they aren't their kids.
* Subverted In ''Series/{{Bewitched}}'': the protagonists are a witch and her non-magical husband. Their daughter has magic powers, while their son at first does not seem to have powers. It turns out he does, but he just didn't use them because his father does not like for them to use their powers.
* Centaurs on ''Series/XenaWarriorPrincess'' are an exclusively male race, they mate with human females and if offspring are male, they are always centaur, female children are always human.
* In the made-for-TV movie {{Series/Hercules}}, wood spirits' gender determines what race they are. Satyrs are always male and nymphs are always female, a child between the two will always be the same race as the gender they share with their parent. A human relationship with a nymph will always result in another human regardless of sex. [[spoiler: Hercules ends up fathering a human son with the his second wife, the nymph Deianeira.]]
* In the werewolf-Series ''Series/{{Bitten}}'' a son between a (human) mother and a (werewolf) father will always be a werewolf. A daughter will always be human.
** Played with: A werewolf can also be transformed via bite, but the protagonist Elena is the only known woman who survived the transformation.

[[folder:Puppet Shows]]
* ''Film/TheMuppetChristmasCarol'': Kermit and Piggy's children are male frogs and female piglets.
* ''Film/MuppetsMostWanted'': Subverted. In Piggy's ImagineSpot, she and Kermit have a piglet daughter and a frog son, but the daughter is green and the son is pink -- unlike in ''The Muppet Christmas Carol''.

[[folder:Tabletop Games]]
* In ''TabletopGame/CastleFalkenstein'', [[OneGenderRace there are only male dwarves and female fairies]]. The solution? Dwarves and fairies can mate -- male offspring always become dwarves, females become fairies.
* ''TabletopGame/DungeonsAndDragons'':
** The TabletopGame/{{Eberron}} campaign setting uses this to escape having to make stats for half-Kalashtar. {{Justified|Trope}} by the spirits which define a Kalashtar bloodline having clearly defined genders; this means a female spirit only manifests itself in the females of its host-lineage, and vice-versa for a male spirit.
*** This trope technically applies to intra-Kalashtar mating as well; sons inherit the spirit-lineage of their father, and daughters that of their mother.
** In the Tormenta setting, minotaurs are a playable race with their own nation inspired on Rome. There are no female minotaurs. They mate with humans (generally their slaves) or Half-Elves, and the males are minotaurs, while the females are from their mother's race.
** This was true of ''AD&D'' 2[-[[superscript:nd]]-] edition in general for [[OneGenderRace One-Gender Fey Races]] like satyrs, nymphs, sylphs or dryads.
** Hags -- a humanoid species based off of fairytale witches -- reproduce by ([[VideoGame/NeverwinterNights2 usually]]) kidnapping and raping human males. Female children of such pairing are always hags, while male offspring are brutish hagspawn that serve hags.
* ''TabletopGame/{{Pathfinder}}'': Hags are AlwaysFemale, and thus need to mate with humanoids, monstrous humanoids or fey to reproduce. The female children resulting from these unions are always hags, while the male children are always members of the father's species, albeit sterile and appearing... [[UncannyValley wrong]], somehow. This is in contrast to ''TabletopGame/DungeonsAndDragons'', ''Pathfinder''[='=]s [[SpiritualSuccessor Spiritual Predecessor]], where the hags originate from and where the results of hag/other unions are either a) AlwaysFemale and always hags, or b) result in female children who become hags and male children who become hulking, misshapen monsters called hagspawn, with little resemblance to their father's species.
* In the systemless [[http://www.amazon.com/dp/B0040JHT06 Zodiacs]] campaign guide, it is mentioned that any child has roughly a 3 in 4 chance of being the same species as their mother.
* Downplayed in the ''TabletopGame/HcSvntDracones'' setting. Vectors are, essentially, a genetically engineered race of FunnyAnimals (with minor variations allowing for both LittleBitBeastly and {{Talking Animal}}s). However, their creators explicitly included 'mutt reduction blocks' in their genetic code; a child of a cat and a dog has about a forty-five percent chance of being either a cat ''or'' a fourty five percent chance of being a dog, no matter their gender, and a ten percent chance of being either one of the other many races or having a mutation their parents didn't (which does include hybridization of the parent races as a possibility).

[[folder:Video Games]]
* ''Franchise/{{Pokemon}}'': Usually, the child of two different Pokémon will always be the same species as the mother, unless the mother is a Ditto. For male-only species, such as Tauros and Hitmontop, they can only reproduce their own species by breeding with Ditto. Oddly, a Ditto can breed with any breedable Pokemon ''except'' another Ditto. However, certain Pokémon have genders so different that they are classified separately, but the above rules still apply when crossbreeding (e.g. the child of a female Nidoran will be a Nidoran of either gender, but the child of a male will be whatever species the mother is.) See also: HotSkittyOnWailordAction.
* Lampshaded in ''VideoGame/KnightsOfTheOldRepublic 2'', with a Human sub-species or variant species that ''specifically'' works this way, the Echani. The somewhat creepy Echani Handmaidens all look identical because Echani always physically take after the parent of the same gender. The one exception is a pariah because the fact that she looks different is a sign of their father's infidelity -- and because she looks exactly identical to her mother at her age. The creepiness is enhanced by [[spoiler:the credible fan theory that the Handmaiden's mother is Kreia]].
* ''VideoGame/ChibiRobo'' extends this trope to LivingToys. [[spoiler:The son of Mort and Princess Pitts is a mummy action figure (like Mort), the daughter is a princess doll like Pitts.]]
* ''Franchise/FireEmblem'':
** In the epilogue of ''[[VideoGame/FireEmblemTellius Fire Emblem: Radiant Dawn]]'', the player learns that the children of [[{{Animorphism}} half-human half-animal shapeshifters]] [[spoiler:raven king Naesala and heron princess Leanne]] are [[spoiler:a raven boy and a heron girl]].
** Averted elsewhere in ''[=PoR=]'' and ''RD'' however -- notably, the child of a beorc and a laguz will not follow the species of either parent. They will instead have a human body, with heightened powers and longevity from their laguz blood. For a more specific example [[spoiler:Soren's looks trend much more toward his mother than his father, but he resembles neither closely enough to be identified as their child on sight, although he bears a reasonable resemblance to his uncle in hindsight.]]
** Meanwhile, in ''VideoGame/FireEmblemAwakening'', any children born to Nowi, Nah, or Tiki will always be female. All three being [[OurDragonsAreDifferent Manakete]] may have something to do with this, but the fact that male Manakete have been shown before in the franchise makes this unlikely. Though the reason for this is actually due to gameplay reasons. Nowi always gives birth to Nah, and all three can give birth to Morgan, but only female Morgan as she will always be male Avatar's child.
** Averted in the same game by [[ProudWarriorRaceGuy Panne]], a Taguel (Rabbit Person). While she is the only one of her kind, her child is always a male. She has a male and a female if the Avatar is her husband.
* ''Franchise/TheElderScrolls'': As the series' averts AllGenesAreCodominant, offspring produced by members of two different races are {{Uneven Hybrid}}s with the race of the offspring usually being virtually identical to the mother, with a few of the father's traits potentially sprinkled in. The [[LizardFolk Argonians]] are the only race not to share evolutionary origins with the others and are mutually infertile with everyone except each other, while [[CatFolk Khajiit]] may be able to interbreed, but to date, there are no canonical examples of offspring produced.
* The ending of ''VideoGame/{{Grandia}}'' shows Justin and Feena several years later, married, with a bunch of little-Justins and little-Feenas running around.
* The Gerudo from ''VideoGame/TheLegendOfZeldaOcarinaOfTime'' and ''VideoGame/TheLegendOfZeldaBreathOfTheWild''... maybe. The Gerudo are an all-female tribe of desert bandits that produces a male every one hundred years. In order to procreate, they have kids with Hylian men, with the ''Breath of the Wild'' Gerudo even having special classes on how to interact with men. It's ''possible'' that the union of a Gerudo woman and a Hylian male produces either a female Gerudo or a male Hylian, but other than the above information there is no evidence of this in-game.
* In ''VideoGame/SaGaFrontier2'', Cordelia (called Cody by Wil) is Wil's initial love interest and the mother of Wil's son, Rich. Depending on the player's choice, though, Cordelia can die, leaving Wil to marry Labelle instead. However, despite obviously not being Cordelia, Labelle still gives birth to the exact same son.
* {{Averted|Trope}} in ''Franchise/MassEffect'''s [[OneGenderRace monogendered]] [[GreenSkinnedSpaceBabe asari]] species. Any reproductive pairing will end up with the child being asari as well. This is because asari [[BizarreAlienReproduction do not reproduce sexually like other species]], but instead use their finite control over their nervous system to [[ExoticEquipment copy part of their partner's genetic code into their daughters']], which is then carried to a full-term pregnancy as would be expected of a near-human humanoid.
* Averted in ''VideoGame/{{Solatorobo}}'': Felineko and Caninu can interbreed, but the children are either Caninu or Felineko with no regard to gender.
* Kokonoe from ''VideoGame/BlazBlue'' looks very similar to her mother, a humanoid witch, but has a few traits from her intelligent feline father Jubei [[LittleBitBeastly including two tails and cat ears]].
* Downplayed in ''Franchise/DragonAge'' with the Orzammar dwarves' caste system: each dwarf belongs to a specific caste from birth, whereby boys inherit their father's caste, while girls inherit their mother's. This gives rise to the "noble hunting" activity, where young hopefuls (mostly women) of low castes seek to seduce members of higher ones (usually nobles) and to sire children with them, who would hopefully belong to the higher caste. If successful, the "noble hunter" can become a concubine/consort for as long as the child survives. Paradoxically, this behavior is not only tolerated but even surreptitiously encouraged by the nobles, since their birth rates are in decline, and a kid by a "hunter" is as legal an heir in Orzammar as by a noble spouse.

[[folder:Web Comics]]
* Lampshaded in ''Webcomic/TheClassMenagerie'' webcomic, where gender and species are explained as being based on that of the parents.
* Averted in ''Webcomic/KevinAndKell'' -- while still managing to [[ArtisticLicenseBiology fail biology]] -- in which little Coney, daughter of a female wolf and a male rabbit, is an omnivorous bunny; she's mostly represented in the strip as being carnivorous, much to the surprise of a lot of her prey, but she can and does eat vegetables as well.
* ''Webcomic/DanAndMabsFurryAdventures'':
** Jyrras and his sisters. Their dad is a kangaroo mouse while their mom is a kangaroo. Yes, he gets glomped a lot by his much bigger siblings, why do you ask?
** Though when beings and creatures (demons, cubi etc.) interbreed their offspring look like their being parent with creature traits tacked on, regardless of gender. For example Lorenda is a half-demon cow, her mother is a demon mare and her father was a bull being. Likewise both Dan and Abel heavily resemble their being parent, and Dan's [[http://www.missmab.com/Demo/HG02.php hypothetical daughter with Matilda]], a taur Mythos, strongly resembles her mother.
** And then there's the issue of body type, children will always take on the type of their mother; i.e. a [[OurCentaursAreDifferent taur]] mother will always have taur children, same with bipedal and [[SnakePeople serpentine]] body types. Amber made the rule on the fly [[FridgeHorror when she considered a taur being born to a non-taur mother]].
* Inverted in ''Webcomic/{{Precocious}}'', Bud is a Scottish fold like his mother, while his older sister is a white American shorthair like their dad.
* ''Webcomic/NamirDeiter's'' sequel comic, ''Nicole and Derek'' has the variant of "same gender parent's physical appearance, opposite's coloration." Nicole is a rabbit like her mother, but has her (hedgehog) father's brown "headfur" and glasses. Derek's parents are both cats, so he's basically a younger version of him with his mother's fur pattern.
* Inverted in ''Webcomic/PicpakDog''. Picpak's son resembles his mother, a blue cat.

[[folder:Web Original]]
* Somewhat justified with chakats and skunktaurs in the ''Literature/ChakonaSpace'' stories. They're both [[{{Hermaphrodite}} hermaphroditic]] species (though chakats are parallel and use more feminine terms, while skunktaurs are [[GenderBender sequential]] and tend to be more masculine) and their genes are dominant to most dioecious species that they are compatible with. And when they interbreed their cubs are the same species as the mother, making it possible for a chakat to have a "brother" who is the same species as hir father, but a skunktaur's "sister" would be like hys father.
* In general this is something that pops up frequently in the UsefulNotes/FurryFandom when an artist/writer doesn't want to bother too much with genetics if two races can cross-breed at all, but more often you'll wind up with PatchworkKids or a HeinzHybrid when one wants their fursona to be unique.

[[folder:Western Animation]]
* ''WesternAnimation/FamilyGuy'': Herbert's dream sequence parody of "Somewhere That's Green" from ''Theatre/LittleShopOfHorrors''. In it, Herbert is dressed like Audrey and Chris is his Seymour. And the son and daughter look like Chris and Audrey!Herbert respectively. It's [[UncannyValley really weird]] compared to where the parody came from which shows that Seymour and Audrey's children look like miniature versions of their parents.
* ''WesternAnimation/GoofTroop'': Pete (a cat) and Peg (presumably a dog)'s children. P.J. looks just like Pete (with less of the ugly), and their daughter Pistol looks more like Peg. However, given that the majority of the characters in the show are DogFaces and the concept of "breeds" does not seem to exist in the ''Goof Troop'' continuity, Pete may in fact be a dog in this series, making this an example of the supertrope StrongFamilyResemblance.
* Played with in ''WesternAnimation/RockosModernLife'', where the children (born from an egg) of Filburt the turtle and his feline wife Dr. Hutchison follow this trope, except for one child being a steer who resembles Heffer who actually sat on the egg until it hatched (a ShoutOut to the Creator/DrSeuss book ''Horton Hatches an Egg'').
* Hinted at in a painting that Painter Smurf had created of Papa Smurf and his prospective bride Flowerbell the woodnymph in ''WesternAnimation/TheSmurfs'' episode "Papa's Wedding Day", with their offspring male Smurfs. The painting was done to dissuade Papa Smurf from marrying Flowerbell, as the other Smurfs knew the whole thing was a setup.
* Averted in ''WesternAnimation/TheFairlyOddParents'' television movie, ''Channel Chasers'', where in an improved future shows a grown-up Timmy (who has married his AbhorrentAdmirer Tooty), with two children; Timmy s' son looks like him, but wears a different hat, has black hair like Tootie, and a pointy nose. Timmy's daughter looks like a female version of himself, with better teeth and tweezed eyebrows, and wears similar sunglasses and clothes to Tootie, and has a hairstyle similar to Timmy's childhood crush Trixie (as Timmy's eventual marriage was meant to be a secret at this point)
* ''WesternAnimation/RegularShow'': [[spoiler:Margaret is a red robin like her mother (and the rest of her extended family, save John) while her father is a ''human''.]]
* Hobart's puppies in ''WesternAnimation/{{Dogstar}}''. The girl puppies look exactly like their mother Lady, while the boy puppy looks exactly like Hobart.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' is surprisingly good at averting this. Nine out of ten ponies do not directly resemble their parents. A few ponies significantly resemble a parent (such as Rarity and Pumpkin Cake, who both look like their fathers), others share apparent physical traits (Sweetie Belle is white like her father, Rainbow Dash has her father's hair and Pinkie Pie has her mother's eye color), and many more seem to instead resemble relatives (Applejack and Apple Bloom are shown to look like distant aunts).
* ''WesternAnimation/{{Wakfu}}'' inverts this trope with [[spoiler: Evangelyne and Sadlygrove's children]], as each kid is the same race as their opposite sex parent.
* BojackHorseman has evidence for and against this being a hard and fast rule.
** Played straight with Charlotte (a deer) and Kyle (a human) and their two kids, Penny (a deer) and Trip (a human).
** Averted in [=BoJack's=] dream sequence in "Downer Ending", in which he imagines he and Charlotte are married and their child Harper is a horse. It is debatable whether a dream would follow real-world rules.
** In the third season finale, a female horse presumed to be [[spoiler:[=BoJack's daughter=]]] is shown; unless her as-yet-unseen mother is also a horse, this rule may not apply.
*** She turns out to be the child of [[spoiler:[=BoJack's=] father and a human woman, so it doesn't.]]
