Gender Equals Breed

"All of the girls look exactly like Mommy and all of the boys look exactly like Daddy! [beat] This is not how biology works!"
The FanFiction Critic, review of The Affair

Two-species couples open up a lot of questions about what 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. note  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. 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. See more on that here.

Sub-Trope to Either/Or Offspring, which is about offspring of two-species couples only inheriting one species in general; and Lineage Comes from the Father, though in this trope, the daughter takes after the mother instead. Sister Trope to Dominant Species Genes, where one species dominates regardless of gender. Compare with Bizarre Sexual Dimorphism, where a single species has very different-looking genders, and Patchwork Kids, where the children look (and often act) like a perfect mix of the parents. (Of course, with Tertiary Sexual Characteristics, 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 One-Gender Race, although it does make a pretty good excuse.

Compare Jacob and Esau. Bicolor Cows, Solid Color Bulls is a subtrope.

  • The Burger King, in commercials, 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 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 two hippo sons, one slightly larger than her, and one who is a baby that is practically the same size as her. Just think about that for a while (or rather, don't).
  • In a Japanese commercial for the heavily advertised Solatorobo (a mecha game featuring anthro characters), this trope is illustrated at first between an interspecies couple and then subverted when a hybrid is shown! Here’s to hoping Cheetahs and Bulldogs never mate.

    Anime & Manga 
  • Fullmetal Alchemist: In the ending, Ed's son retains the Xerxesian racial traits of his father and grandfather, while his daughter is an ordinary Caucasian girl like her mother.
  • Trigun: Inverted in an unusual case 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.
  • Tweeny Witches: Downplayed with Lennon. He is the son of a witch and her human husband. He has blonde hair, grey eyes, fine features, and magical powers from his mother's side of the family, but Sheila manages to discover his human heritage because he lacks the vestigial wings of the witches and warlocks.
  • YuYu Hakusho: This is sort-of the case of Hiei and Yukina, 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.

    Comic Books 
  • Archie Comics: One Fairy Tale Episode has Archie and Betty marry and have lots of Babies Ever After. The daughters are all miniature-Betty, while the sons are all minuature-Archie, with the occasional hair color swap.
  • Blacksad: The chief of police in the third issue is 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.
  • Dino Boy: Invered. Dino-Boy is 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 his daughter is like her father.
  • For Better or for Worse: Michael resembles John and Elizabeth resembles Elly.
    • This is carried over into the next generation, with Meredith resembling Deanna and Robin resembling Michael. Francoise also resembles her biological mother Thèrése.
    • Subverted with April, who looks like Elly but has John’s hair color.
  • Sonic the Hedgehog (Archie Comics):
    • This is the way Sonic and Sally's children are represented in all of the flashforwards in the comic. The "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 Depending on the Artist, the boy may have Bunnie's coloration and the girl Antoine's. Somehow, they 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 "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.
  • Usagi Yojimbo: Subtly utilized (all previous pairings being same-species) when Ino (a pig) and his wife (a... 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.

    Fan Works 
  • In The Bridge this is how mermare reproduction works. Mermares are a One-Gender Race, 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.
  • Cat Fire Hawk is a piece of Sonic the Hedgehog fanart that depicts Blaze the Cat and Jet the Hawk as siblings. Blaze takes after her mother, and Jet takes after his father.
  • Extended Stay: Played straight with the Warden and the Mistress's twins Matilda and Ethan in that both of them look like miniature versions of their parents. They even wear the same clothes their parents have worn. Combined with Strong Family Resemblance.
  • Discussed in Offspring. According to Link's daughters, Zora and Rito can both interbreed with Hylians, but the race of the mother determines the race of the offspring, in part because Zora and Rito lay eggs whereas Hylians give live birth.
  • Weres Harry?: Veela are all female and reproduce with human men. Any female children will be veela, while any male children will be ordinary (if extremely handsome) men.
  • Wishing Well: Male ponies are born resembling their father and females are born resembling their mother. Upon reaching adolescence, ponies gain more individual appearances.

    Films — Animation 
  • Balto II: Wolf Quest: Inverted, as the eponymous wolf/dog hybrid's litter with his red-furred Husky Love Interest 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.
  • Lady and the Tramp: At the end, three of the puppies look like pure-bred cocker spaniels like Lady, while the boy Scamp looks just as much like a schnauzer mix as his father. They should ALL be mongrels to one degree or another. In the film sequel Lady and the Tramp II: Scamp's Adventure the cockers are all female, but the earlier newspaper strip on which it was partially based averts this by making one of the cockers a boy.
  • Open Season: In the 3rd sequel, Elliot and Giselle end up with two baby does and one buck, with the does looking exactly like their mother (the only difference being the color of noses — red and black), and their son the exact copy of his father.
  • Rover Dangerfield 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.
  • Song of the Sea: Ben and Saoirse are both half-selkie, half-human. However, Ben is identified as a human, like his father, and Saoirse is identified as a selkie, like her mother. Saoirse becomes completely human at the end, though, since she had to give up her selkie powers in order to stay in the human world.
  • Treasure Planet: The children of Delbert and Amelia display this. The three girls are clearly modeled after their mother and the boy is clearly modeled after his father (even inheriting his poor eyesight). They aren't even the same species!

    Films — Live-Action 
  • Honey, I Shrunk the Kids: The Szalinski family. 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 Mom and Dad Save the World, 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 The Belgariad, the imperial family of Tolnedra frequently intermarries with dryads. The daughters of the family (such as Ce'Nedra) are all dryads, while this doesn't seem to have any effect on the male line.
  • "The Children of the Owl and the Pussycat", Edward Lear's sequel to "The Owl and the Pussycat", unpublished in his lifetime, states:
    The brothers of our family have feathers and they hoot,
    While all the sisters dress in fur and have long tails to boot.
  • Codex Alera:
    • 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 from another continent), leading to rumors that there just weren't any, and more rumors about the purpose of the captives they take in their periodic raids of Alera’s shorelines. Later it turns out there are plenty of females, Canim society is just male-dominated.
  • In The Heroes of Olympus 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 One-Gender Race.
    • In the sequel series "The Trialsof Apollo" a male dryad (wooden nymph) named Joshua is introduced. Apollo comments that male dryads are quite rare.
  • In Myth Adventures, trolls and trollops are the same species. Trolls are seven-foot tall Genius Bruisers that are covered in shaggy green fur and use Obfuscating Stupidity when outside of their home dimension so that people think they're Dumb Muscle. Trollops are Statuesque Stunners with green hair but otherwise look like normal humans and have a reputation for promiscuity. Which is not because they dislike trolls: they find trolls very attractive,they just happen to find the men of many other races equally attractive.
  • In Northern Lights, witches are an all-female species that mate with human males. Female offspring are witches, male offspring are human.
  • In Piers Anthony's 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).

    Live-Action TV 
  • Bewitched: Subverted. 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.
  • Bitten: A son conceived by a human mother and a werewolf father will always be a werewolf. A daughter will always be human.
  • 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. Hercules ends up fathering a human son with the his second wife, the nymph Deianeira.
  • Scrubs: This concept is parodied and then subverted when the Almighty Janitor 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.
  • Xena: Warrior Princess: Centaurs are an exclusively male race. They mate with human females and, if offspring are male, they are always centaurs. Female children are always human.

    Puppet Shows 

    Tabletop Games 
  • In Castle Falkenstein, there are only male dwarves and female fairies. The solution? Dwarves and fairies can mate — male offspring always become dwarves, females become fairies.
  • Dungeons & Dragons:
    • This is often true of one-gender fey races like satyrs, nymphs, sylphs or dryads. Dryads and nymphs, for example, can have children with satyrs; if these are boys they'll be satyrs, but if they're girls they'll belong to their mother's species.
    • Hags — a humanoid species based off of fairytale witches — reproduce by (usually) kidnapping and raping human males. Female children of such pairing are always hags, while male offspring are brutish hagspawn that serve hags and have little resemblance to their father's species.
    • Eberron uses this to escape having to make stats for half-kalashtar. Justified 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.
    • Tormenta: Minotaurs are a playable race with their own nation inspired by 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.
    • Werebunnies, a creature invented by fans for Planescape by fans, are an always-female race who reproduce by mating with males from other races. Daughters are werebunnies, and sons are whatever race the father is. Werebunny pregnancies always result in the birth of male/female pairs of twins too.
  • Hc Svnt Dracones: Downplayed. Vectors are, essentially, a genetically engineered race of Funny Animals (with minor variations allowing for both Little Bit Beastly and Talking Animals). 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).
  • Pathfinder: Hags are Always Female, 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... wrong, somehow.
  • Zodiacs: In the campaign guide, it is mentioned that any child has roughly a 3 in 4 chance of being the same species as their mother.

  • Tamagotchi: The Mesutchi and Osutchi played this straight, with only the baby and child stage characters looking alike. In the 2000-era toys, it's primarily used for the babies, but later versions made some gender-neutral breeds into gender-exclusive. For example, Mametchi was neutral from V1 through V3, but exclusively male from the Entama/V4 onward.

    Video Games 
  • BlazBlue: Kokonoe looks very similar to her mother, a humanoid witch, but has a few traits from her intelligent feline father Jubei including two tails and cat ears.
  • Chibi-Robo! extends this trope to Living Toys. The son of Mort and Princess Pitts is a mummy action figure (like Mort), the daughter is a princess doll like Pitts.
  • Dragon Age: Downplayed 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.
  • The Elder Scrolls: As the series' averts All Genes Are Codominant, offspring produced by members of two different races are Uneven Hybrids 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 Argonians are the only race not to share evolutionary origins with the others and are mutually infertile with everyone except each other, while Khajiit may be able to interbreed, but to date, there are no canonical examples of offspring produced.
  • Fire Emblem:
    • In the epilogue of Fire Emblem: Radiant Dawn, the player learns that the children of half-human half-animal shapeshifters raven king Naesala and heron princess Leanne are 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 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 Fire Emblem: Awakening, any children born to Nowi, Nah, or Tiki will always be female. All three being 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 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.
    • A few notable inversions occur in Fire Emblem Fates:
      • Keaton, the male Wolfskin, can marry a human girl from the group or a female Avatar, and will have a Wolfskin daughter.
      • Kaden, the male Kitsune, will also have a daughter, who is a Kitsune like him.
      • If either Keaton or Kaden marries a female avatar or Azura, though, their potential sons will take after their mothers.
      • The Avatar, regardless of who they marry, will always produce a child of the opposite gender as themselves that inherits their dragon abilities.
  • Grandia: The ending shows Justin and Feena several years later, married, with a bunch of little-Justins and little-Feenas running around.
  • The Legend of Zelda: Ocarina of Time: The Gerudo and The Legend of Zelda: Breath of the Wild... 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.
  • Knights of the Old Republic: Lampshaded in 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 the credible fan theory that the Handmaiden's mother is Kreia.
  • Pokémon: 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: Hot Skitty-on-Wailord Action.
  • In SaGa Frontier 2, 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.

  • The Class Menagerie: Lampshaded, as gender and species are explained as being based on those of one's parents.
  • Dan and Mab's Furry Adventures:
    • 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 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 taur mother will always have taur children, same with bipedal and serpentine body types. Amber made the rule on the fly when she considered a taur being born to a non-taur mother.
  • Kevin & Kell:
    • Aversion: while still managing to 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.
    • Inversion (with a mix of Random Species Offspring, of all tropes): Francis is the son of the fennec fox George and the rabbit Danielle. At first he looks like an aversion as he isn't easily identifiable and has omnivore teeth, however he eventually turns human...which is what Danielle was before crossing over to the Funny Animal side of the dimensional portal.
    • Likewise, the All There in the Manual side Twitter also has an inversion by way of Random Species Offspring: the former vulture, now human Catherine gives birth to a bear cub daughter, which is what her father would be if he went to Domain.
    • Another aversion: Lindesfarne and Fenton's daughter Turvy is a patchwork kid, being a hedgehog with bat wings.
  • 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 his dad with his mother's fur pattern. Derek's cousin, Cerise, has the same pattern with her parents.
  • Picpak Dog: Inverted. Picpak's son resembles his mother, a blue cat.
  • Precocious: Inverted; Bud is a Scottish fold like his mother, while his older sister is a white American shorthair like their dad.

    Web Original 
  • Chakona Space: Chakats and skunktaurs are both hermaphroditic species (though chakats are parallel and use more feminine terms, while skunktaurs are sequential and tend to be more masculine) and their genes are dominant to most dioecious species that they are compatible with. 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 Furry Fandom 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 Patchwork Kids or a Heinz Hybrid when one wants their fursona to be unique.

    Western Animation 
  • The Amazing World of Gumball: Inverted, with Gumball being a cat like his mother Nicole, and his sister Anais being a rabbit like their father Richard. Likewise Richard’s own mother is also a rabbit, while his father is a rat.
  • Bojack Horseman 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 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 BoJack's father and a human woman, so it doesn't.
    • In the fourth season, when Princess Carolyne (a cat) gets pregnant by Ralph (a rat), at one point he asks if the doctor already told her which species the baby is, which is also a evidence against this trope.
  • Dogstar: Hobart's puppies. The girls look exactly like their mother Lady, while the boy looks exactly like Hobart.
  • Family Guy: Herbert's dream sequence parody of "Somewhere That's Green" from Little Shop of Horrors. 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 really weird compared to where the parody came from which shows that Seymour and Audrey's children look like miniature versions of their parents.
  • Goof Troop: 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 Dog Faces 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 Strong Family Resemblance.
  • Regular Show: Margaret is a red robin like her mother (and the rest of her extended family, save John) while her father is a human.
  • Rocko's Modern Life: Played with, as 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 Shout-Out to the Dr. Seuss 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 The Smurfs 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.
  • SpongeBob SquarePants: Mr. Krabs is a crab while his daughter Pearl is a whale. According to an official trivia book written by a writer for the series, Pearl takes after her Missing Mom.
  • Wakfu inverts this trope with Evangelyne and Sadlygrove's children, as each kid is the same race as their opposite-sex parent. Though in this world, the "races" are in fact religions granting an appearance close to their gods, and they are still the same species. Their third child is also a boy who takes more after his father (though he does have green eyes like his mother).

    Real Life 
  • A small number of amphibian species are exclusively female and have so-called "parthenogenetic-like" strategies in which they mate with males of other species, but always produce females of their own species. Usually this involves mating with a male but either ignoring the male's genetic material, or including it but only expressing the female's genetics, resulting in children that are practically clones of the mother.
  • Some species, like water frogs, produce hybrid children that have both mother and father's genes, but will always pass all of the grandmother's genes on to the child without passing any of the grandfather's genes. This ensures that children will always have 50% of the mother species's DNA, even after generations of mating with the father's species. This results in a system where the children are both true hybrids and also arguably always the mother's species, as their children will always have the same 50% DNA of the mother.
  • This is a played with example with calico and tortoiseshell cats, as, because of the genetics of their colorings, they're usually female, with male ones being a rarity with the odds being 1/1000-1/3000. Similarly, you get red tabby cats, with 80% being male and 20% being female.
