Hollywood Genetics

Go To
Red hair is a recessive trait. Assuming both parents carry the gene,
any child of theirs would have a 1/4 chance of having red hair.
The chances of 3 kids in a row being born with red hair is 1/64 - possible, but extremely uncommon.

"Glynnis, she has a birth certificate, she has my photograph, and she has my eyes."
Lord Henry Dashwood (brown-eyed Colin Firth) on his daughter Daphne (green-eyed Amanda Bynes), What a Girl Wants

We all know the basic Mendelian model of inheritance; traits are usually either dominant or recessive. Having one copy of a dominant allele means that the person will express the dominant trait, and the only way for someone to express a recessive trait requires having two copies of a recessive allele. Even outside of scientific terms, it's common reasoning that certain traits tend to run in families and we expect relatives to "match" in some way.

These facts are sometimes ignored in Hollywood casting, which can end up having (biological) families looking like just a random group of people. As a result, you'll see blondes having black-haired children, biracial people who look more black/Asian/etc. than their black/Asian/etc. parent, inexplicably large discrepancies in height between parents and children, and so on.


Sometimes families can look so unrelated that it can take focus from the story. "Where did Alice get black hair and brown eyes if Bob and Carol are green-eyed redheads?"

This can even interfere with the plot if a physical resemblance is a plot point (especially in an adaptation when characters get an Adaptation Dye-Job or otherwise don't match the physical description of the character in the original work).

There are certain justifications; the mechanics behind real life genetic inheritance are more complicated than the Mendelian model, which doesn't factor in mutations, malfunctions, and polygenetic traits. Also, casting around to get the most plausible genetics is not always practical—after all, you're not going to turn down Harrison Ford for a part because his eyes are the wrong color. Sometimes it's an Enforced Trope, as having a cast of characters who all look the same is rather boring.


On the other hand, you don't have that excuse in non-visual media or in animation where the powers that be have complete control over how characters look. And you could always give Harrison Ford contacts (or even digitally alter his eye color in post-production).

Compare Identical Grandson, Uncanny Family Resemblance, WTH, Casting Agency?, and Patchwork Kids, which can veer too far in the opposite direction. When done intentionally, the dissimilar child is a Chocolate Baby. Compare also Random Species Offspring when even the species of the offspring is different from the parents. Also see LEGO Genetics, for the Science Fiction take.

    Anime & Manga 
General note before adding examples:note 
  • Dragon Ball was fairly realistic in this, especially considering the prevalence of You Gotta Have Blue Hair, and the exceptions are in the vein of Uncanny Family Resemblance rather than this trope.
    • Bulma has her mother's blue eyes (not obvious since her mother's eyes are normally closed) and her father's purple hair, both of which she passed on to her children Trunks and Bra. Trunks has Vegeta's skin color, eye shape and eyebrows, while Bra is more or less a clone of her mother.note 
    • As a little girl, Krillin and Android 18's daughter Marron looks just like Krillin with 18's hair color, including having no nose. By Dragon Ball GT, she looks just like her mother, and bears little resemblance to her father.
    • Gohan looks like both of his parents, while Goten looks exactly like Goku did in the original Dragon Ball, including his hairstyle. Gohan's daughter Pan in turn inherited the shape of her mother Videl's eyes but his eye color.
  • Naruto averts this in general; if a character has an unusual hair color or facial feature, it's normally accounted for in their family— in the title character's case, his Implausible Hair Color and eye color were inherited from his father, while the shape of his face was inherited from his mother. Sasuke and Itachi Uchiha look exactly like their mother Mitoko except for the creases under their father Fugaku's eyes that Itachi inherited. Sakura's pink hair was inherited from her father (albeit his is a darker shade), while based on her mother's rather extreme bangs it's obvious who Sakura got her Forehead of Doom from.
  • Invoked for the merfolk in One Piece: due to their unusual biology, merfolk carry the genes of all their immediate ancestors, so family members are not even guaranteed to be of the same species. These three are full-brothers. Compare them in both appearance and size to their sister.
  • Chibi-Usa from Sailor Moon generated a ton of Wild Mass Guessing and Fan Wank back in the day because her coloration (pink hair, red eyes) was so different from that of her parents (blonde, blue-eyed Usagi and black haired, dark blue-eyed Mamoru). According to Word of God, her coloration was meant to make her resemble a baby rabbit to match her Punny Name. Also, hair colors in the manga weren't static—sometimes her mother Usagi was depicted with silver hair and even pink hair in her original design. Usagi herself is the daughter of a purple-haired mother and a black-haired, dark-eyed father, and has a brother with light brown hair and dark blue eyes.
  • Tenchi Muyo!:
    • The series is a strong aversion, even regarding facial features. In fact, the only character whose look isn't readily accounted for in their family is Tenchi's mother Kiyone (silver hair and gray eyes while her parents have black hair/brown eyes and green hair/yellow eyes), and since she and her parents are two different kinds of Human Aliens, we have no idea how their genetics exactly work anyway.
    • Actually invoked in the main continuity with Aeka. She was born with curly aqua-green hair like her mother and sister, but later underwent gene manipulation to activate her father's genes for straight purple hair. She wanted her hair to be darker to look more like her black-haired stepmother Funaho so she could win the affections of her half-brother/fiancé, Yosho.
  • Takeshi and his sister from Your Lie in April have blond hair however their parents have dark hair. Similarly, Kaori's parents are brunettes but she has blonde hair. It's even more noticeable because they're the only characters in the series without black or brown hair.
  • Rin from Bunny Drop is a blonde but both her mother and father are black haired (though her father's hair was grey due to age). The manga revealed late into the series that Daikichi's grandfather isn't Rin's biological father. It's possible she got her hair color from her real father.
  • Nagisa Hazuki from Free! is a blond but has brunette older sisters.
  • Pokémon:
    • Cilan, Chili, and Cress are triplets who have green, red, and blue hair, respectively. Their eye colors match their hair colors.
    • According to Pocket Monsters: The Animation, Brock and his siblings are the result of his mother's multiple marriages, yet they all look exactly like Brock's father Flint. The Pokémon anime itself ignores the novel (for what it's worth, the book was written by Takeshi Shudō, the anime's original head writer, and is fairly revisionist in its depiction of events).
    • Misty and her three older sisters have different hair colors: red (orange toned rather than bright red), pink, blue, and blonde. The aforementioned books justify this by saying Misty's sisters wear wigs; however, the anime itself holds no such implications.
  • In the anime adaptation of Higurashi: When They Cry, Rena's parents have brown hair while she is a redhead. Averted in the manga adaptation, however, where Rena inherited her mom's hair colour.
  • Hair color in Beyblade Burst seems random at times.
    • Aiga Akaba has dark brown hair, his father has dark blue hair, his mother has orange/red hair, and his sister has a different shade of blue from their dad.
    • Valt Aoi and his father both have dark blue hair, his mother has black hair, while his twin siblings have bright pink and blue hair, respectively.
  • Towa/Cure Scarlet from Go! Princess Pretty Cure has significantly lighter skin than Kanata, in spite of being his younger sister. Made further complicated since her mother is shown to have dark skin like Kanata, but her father has fair skin, meaning she inherited her skin color from him, which wouldn't make much sense either, since mixed race siblings usually have the same skin tone as each other, meaning she would have dark skin like Kanata.
  • Attacker You!: You has red hair, her father has brown hair, her Missing Mom is revealed to be blonde...just like You's adopted brother who is not related to her anyway.
  • Stop Hibari Kun: Hibari is blonde and has a black haired father. Two of her sisters are blue haired and the other is a brunette.

    Asian Animation 

    Comic Books 
  • Depending on the Artist, Spider-Man's Mary Jane Watson inherited her red hair from her father. Her mother is blonde... which means her mother either dyes her hair or there is a huge elephant in the room, as the older daughter Gayle is a dark brunette. You know, Gayle being the product of an extramarital affair could partially explain why their father was such an Abusive Parent...
  • Despite being a clone of Wolverine, Laura Kinney, a.k.a X-23 of X-Men is portrayed as having similar features to her mother Dr. Sarah Kinney, who, while not genetically related to her, carried her to term. Some stories claim that Dr. Kinney used some of her own DNA to stabilize the sample they had from Wolverine since it was damaged (which is the canon reason she's an Opposite-Sex Clone, since the original sample of Wolverine's DNA was apparently missing its Y chromosome), which would partially justify it
  • Also from X-Men, supervillain Vulcan is the black-haired son of brown-haired Corsair and blonde Katherine Summers. The black hair could be part of his mutation, though.
  • In Injustice: Gods Among Us Black Canary's and Green Arrow's son is a blond, like them. The problem is, Black Canary dyes her hair blonde. She actually has black hair. It's possible the colorists forgot that and made her a natural blonde
  • Robin: Star, a girl Tim befriends while skateboarding, has light skin and blue eyes while her parents and brother are all Ambiguously Brown and seem to have latino or Filipino heritage.
  • In the Elseworlds series Superman & Batman: Generations, both Superman and Lois Lane are black-haired, but their daughter Kara is blond (though both Kara Jor-El and Lucy Lane are blonde, so it's possible that both parents carry the recessive gene)

    Fan Works 
  • Averted and lampshaded in The Second Try. In the notes for chapter 6, the author says that it's "almost blasphemy that he didn't make Aki a chibi-Asuka".

    Films — Animation 
  • In Disney's The Hunchback of Notre Dame, an interracial Official Couple emerged at the end featuring dark-skinned, ethnically Romani Esmeralda and blond, Caucasian adonis Phoebus. Come 2002, a direct-to-video sequel was released, in which Haley Joel Osment plays Esmeralda and Phoebus' son... who is a complete carbon copy of his father besides having his mother's green eyes, being equally blond and white. Dark melanin pigmentation genes are stronger than light ones, and though not entirely dominant, this should result in a skin tone slightly lighter than Esmeralda's. And blond hair is genetically completely implausible with Esmeralda's dark hair being a dominant gene over the recessive gene of Phoebus' blonde hair. In short, the only way to explain the child's completely white appearance is a retroactive Race Lift to Esmeralda, who, ironically, was already subject to a Race Lift in the original, going from a white girl adopted by Roma in the original book to a born one in the film.
  • The Incredibles has Violet, the daughter of blond Bob and redhead Helen, sporting black hair. Unless A) she dyes her hair or B) superhero genetics are different than mortal genetics, this would be flat out impossible in reality, as black hair genes are dominant over red and blond hair genes, and thus her parents wouldn't have carried those genes at all, since their hair isn't black.
  • Inside Out: Mr. and Mrs. Andersen both have brown eyes and brown hair, but their daughter Riley has blue eyes and blonde hair.
    • This is completely possible if both parents carry recessive genes.
  • The Little Mermaid:
    • According to The Little Mermaid III: Ariel's Beginning both Triton and his deceased wife Athena are redheads. Despite this only one of their daughters is a redhead (Ariel). They have two blondes, one raven, and three brunettes. Their children should only have red hair. Either merpeople's dominant and recessive genes are different from humans, or...
    • Queen Athena has a blue tail and King Triton's is blue-green. Their daughters' tails are a literal rainbow (red, orange, yellow, sea green, blue, pink and purple).
    • The Broadway stage production is even weirder, since Triton is black, and his daughters are variously Asian, black, and white with a rainbow of different hair colors. And they all have the same color tail, more or less. Although Broadway is well known for favouring Ability over Appearance.
  • Elsa from Frozen has platinum blonde hair when her father had strawberry-blond hair and her mother had brown hair. It's implied though that her hair color is due to her powers, and if she didn't have them, she would have been either a brunette like her mother or a strawberry-blonde like her father and sister (her eyebrows imply the former).
  • Justified in Tangled with the very blonde Rapunzel being born from two brunette parents, since the hair is explicitly magical as a result of her mother eating the magic flower while pregnant that caused Gothel to later kidnap her, so her hair would be the same color had seen been born normally and once it's cut near the end it's shown to indeed be brown like her parents, which is hinted at by the color of her eyebrows.
  • In Trolls: World Tour, Prince D and Cooper have pink fur, a trait that neither of their parents have.
  • The snowball molly Duchess from The Aristocats has three kittens from the same litter: a similarly white-furred one, a black-furred one, and a red-furred one. Under normal circumstances this is impossible, however there are very complicated ways it can technically occur (such as if their father was a fertile male calico or Duchess was a calico with a white masking gene).

    Films — Live-Action 
  • The DVD cover for Les Misérables (2012) calls attention to a minor example of this trope. Fantine has brown eyes, while her daughter has deep blue eyes as a child, but green eyes as an adult.
  • Terminator 2: Judgment Day has brown-haired, brown-eyed Edward Furlong play the offspring of blonde, gray-eyed Linda Hamilton and blond, blue-eyed Michael Biehn. It's also a retcon because Kyle mentions that John has Sarah's eyes.
  • Many musicals, especially onstage, will completely drop any attempts at realism and go for color-blind casting, often intentionally casting different races in the role of family members. One of the most memorable examples of this in film is Rodgers and Hammerstein's Cinderella starring Brandy. The king is white, the queen is black, and their son is Asian. And it was completely intentional. You're not supposed to care. In the same film, the Wicked Stepmother and one of the stepsisters are white, while the other stepsister is black.
  • Similarly, Kenneth Branagh's Much Ado About Nothing (1993) casts Denzel Washington as Don Pedro and Keanu Reeves as his brother, Don John (the bastard son of their father). Given both that and the relative quality of their acting, it takes quite the Willing Suspension of Disbelief to go along with it. It's possible, however, that they resemble their respective mothers.
  • Freddy's Dead: The Final Nightmare: Red-haired Robert Englund and a red-haired mother equals...dark-haired and olive-skinned Lisa Zane?
  • Fireflies In The Garden casts Ryan Reynolds as the grown-up offspring of Julia Roberts and Willem Dafoe. While this is doubtful, it's not quite as doubtful as the idea of Roberts and Hayden Panettiere being sisters (and as for Panettiere growing up to look like Emily Watson...).
  • In Family Business Sean Connery plays Dustin Hoffman's father, while Hoffman in turn is Matthew Broderick's dad. Riiiiiiiiiiiiiiiiiiiiiiiiiiiiight...
  • Judge Dredd: Dredd is convicted of murder because bullets from a Lawgiver pistol are tagged with the DNA of the Judge who fired them, and forensic examination revealed the tag to match up with Dredd and were actually from his twin brother Rico. It doesn't seem like the DNA should match to begin with, as Rico is clearly not an identical twin of Dredd, which is the only case where they'd have the same DNA.
  • In Warcraft (2016), Australian Travis Fimmel and Irish/Ethiopian Ruth Negga play siblings despite having notably different hair and eye colors and wildly different skin tones.
  • Mrs. Doubtfire: Daniel and Frank are supposed to be brothers, yet are played by Robin Williams (blue-eyed and brown-haired) and Harvey Fierstien (brown-eyed and black-haired), who don't even have a passing resemblance to each other. Fierstein's casting was due to Ability over Appearance.
  • The entire premise of Twins is essentially this. Long-lost fraternal twin brothers Julius and Vincent Benedict are portrayed by tall, muscular, handsome Arnold Schwarzenegger and short, chubby, homely Danny DeVito. Nobody believes they are twins (Vincent himself doesn't believe it until about halfway through the movie), but their differences in appearance are justified, as they are the product of a genetic experiment meant to make the "perfect" human by combining the reproductive material of six athlete and scholarly fathers. Unfortunately, the embryo didn't split equally and Vincent was saddled with all the genetic garbage while Julius got all the desirable traits.
  • All over the place in The Addams Family. Then again, they are Ambiguously Human after all. (That's not even going into Cousin Itt...).
    • Gomez and Morticia Addams have black hair, as does Wednesday. Pugsley, on the other hand, has light brown hair (Fester is shown to have brown hair when he doesn't shave his head, so it likely comes from Gomez's side of the family after all).
    • Gomez is an olive-skinned Dashing Hispanic. His brother, Fester, is pale and homely, with no such accent.
    • Amanda Buckman in Addams Family Values (who is, as far as we know, a regular human) is blond, but her parents have black (her father) and auburn (her mother) hair.
  • Imitation of Life (1934) has Delilah, played by the very dark Louise Beavers and her fair-skinned daughter, played by Fredi Washington. The latter was in fact a fair-skinned black actress, but it's still a bit surprising that Delilah could have a child as light as Peola. The 1959 remake cast a slightly lighter-skinned actress in the mother role, possibly to make it more believable.
  • Home Alone: Kevin McCallister has blond hair. His mother is a redhead, and his father and siblings have dark hair (his sister Linnie was also blonde in the first film, but was recast with a brunette actress in the second film). Kevin's aunt and a few of his cousins are blond, but the aunt is not blood-related.
  • Margarita with a Straw: Laila is played by an ethnic French actress born in India with a skin color much lighter than the actors playing her parents and brother, along with their features being very distinct. Therefore they don't look related at all to her.
  • Love Jacked: Maya is played by Amber Stevens West, who's mixed race and thus much lighter-skinned than both her on-screen parents. Similarly Naomi, her cousin, is also played by a mixed race actress unlike the rest of their black family. It looks pretty jarring as a result.

  • Harry Potter:
    • Similar to the examples in the film series, J. K. Rowling really didn't pay attention in high school bio. Though magical abilities seem to act recessively (e.g. two non-magical parents can have a magical child), Rowling ''says'' that it's actually dominant and can "become dormant" in certain lineages and resurface later (this would explain Squibs — muggles from magical families).
    • Magical abilities actually seem to act dominantly at times (when two magical people produce a Squib, for example), while acting recessively at other times (when two non-magical people produce a magical person because a distant ancestor had magical abilities). And that isn't even getting into the other abilities that can be passed down (Parseltongue, Metamorphagus, Harry's always crazy black hair).
    • Believe it or not, one fan explained a method, and wrote a six page biological paper on it. It utilizes the mechanism of single nucleotide repeats, the same mechanism for Huntington's disease.
  • A plot point in A Song of Ice and Fire. King Robert Baratheon had black hair and blue eyes and Queen Cersei Lannister is blond with green eyes and all three of their children are blond with green eyes as well. But all of Robert's known bastards are black-haired and every other time their houses have intermarried the children have had black hair so Ned Stark figures out that Cersei's kids were actually sired by her brother. It's plausible to put the Baratheon children's paternity in doubt, since having three children in a row with the same recessive trait only expressed by one parent is unlikely, but having a trait stick so tenaciously to one family after centuries of mixed breeding is extremely unlikely. A child has to inherit one allele or another from each parent, even if it isn't expressed.
  • In many of the Chivalric Romances, Percival has a half-brother with a white father and black mother. The brother is piebald (that is to say, he has light and dark patches of skin like a checkerboard), as some horses and dogs do. Clearly, however wrote these stories didn't know how real people of this parentage look.
  • In The Hunger Games Katniss has the same typical Seam traits as her father - dark hair, grey eyes, olive skin. Her sister Prim, however, managed to inherit their mother's merchant look with blonde hair, blue eyes, and fair skin. One might wonder how that was possible when it's strongly implied that townfolks and people in the Seam haven't interbred for generations. It's possible that their father carried those genes too but it's highly unlikely. This has even spawned a fan-theory that Prim is Katniss' half-sister and that she might even be half-sister to blonde, blue-eyed Peeta (whose father had a romance with Katniss' mother when they were young).
  • None of the Erin's care much for biological accuracy when it comes to Warrior Cats. There are numerous characters such as Graystripe, Lionblaze, Brambleclaw, Sandstorm, Ivypool, Mistyfoot, and Scourge who are either impossible for their parentage or are just plain impossible for cats, period.
  • Stray:
    • Pufftail is a brown tabby with white markings. He can't remember his mother, but he assumes his mother is also a tabby with white markings. Pufftail's brother Bootsie is a black-and-white tom. Pufftail's family isn't genetically possible for cats.
    • Pufftail is a brown tabby with white markings while Tammy is a grey tabby with white markings. Somehow, their two sons are ginger.

    Live-Action TV 
  • A common joke in 7th Heaven's hatedom was Little Miss Snarker Ruthie Camden either being adopted or the product of an affair with the gardener, because Mackenzie Rosman has a noticeably darker complexion and less WASPy features than the rest of her TV family.
  • Dawn Summers from Buffy the Vampire Slayer, is a magically-created clone of her sister Buffy, which would essentially make them identical twins. What little resemblance the actresses share to begin with is undermined in later seasons when Michelle Trachtenberg goes through a growth spurt and ends up much taller than Sarah Michelle Gellar.
  • Jasmine on Season 4 of Angel is black (played by Gina Torres); her parents (such as they were), Cordelia and Connor, are not. This is a sci-fi/fantasy show, and she isn't a human so much as a goddess of vast power that uses a glamour at all times to look like that (her real appearance gave her sickly, green-tinged skin, with perpetual maggots crawling out of her mouth and eye sockets).
  • Brown-haired, brown-eyed Hollywood Nerd Toby Isaacs on Degrassi The Next Generation has a blond, blue-eyed father and a redheaded, green-eyed mother.
  • Dexter has Rita and ex-husband Paul, both blond. Their kids Astor and Cody have medium to dark brown hair.
  • Kim Parker from The Parkers is significantly shorter (her actress Countess Vaughn is 4'11") than both her parents (played by the 5'9" Mo'Nique and 6'4" Tommy Ford). Lampshaded by an Enfante Terrible in one episode who, when told by Kim that both her parents were tall, responded with Mama's Baby, Papa's Maybe. Kim is also much lighter than both parents, but due to a great deal of African-Americans having recent white ancestry, this is not as implausible.
  • The Cosby Show: Cliff is noticeably darker than both of his parents. Sondra and Denise Huxtable are both noticeably lighter than their parents. Actress Lisa Bonet's real mother is in fact a white Jewish woman.
  • In Dirty Sexy Money, Juliet has brown eyes while her parents are both blue-eyed. This is actually possible in real life genetics, due to how complicated eye inheritance really is.
  • Clarissa's brother Ferguson in Clarissa Explains It All is the only redhead in a family of blondes.
  • Lampshaded on the "Hackidu" episode of Everybody Loves Raymond. Ray and Debra have dark hair, while the kids have blond hair. Ray trades Ally's $65 "Hackidu" card to Bill Parker, a blond guy. After getting teased for being scammed, Ray decided to get the card back.
    Ray: [to Debra] I'm going to go see your boyfriend. [leaves]
    Marie: Boyfriend?
    Robert: You know, this could explain why all the kids are blond.
    Debra: And smart.
  • Family Ties:
    • This was an early concern during casting: Michael J. Fox almost didn't get the role of Alex P. Keaton because the producers at NBC didn't think it was realistic that the 5'4" Fox could be the son of 6'4" Michael Gross and 5'7" Meredith Baxter.
    • While it's not really viewed this way by viewers, Meredith Baxter said in an interview that she was surprised to see someone as beautiful, dark and kind of exotic as Justine Bateman being cast with such a white-bread looking family.
  • Seemingly averted, but actually played straight in an episode of House. A patient in an early episode found out that he was adopted because, as he claims, parents without cleft chins can't have a child with one, and the doctors agree with this claim. In fact, such a parent-child scenario is possible— just unlikely. Based solely on that trait, the patient shouldn't have been able to tell either way if he was adopted, and Foreman (correctly) explains that while it's unlikely for him to be his parent's child, it's not impossible.
  • A plot point in Game of Thrones, despite being set in a world with no knowledge of genetics. All three "Baratheon" children all have blonde hair and green eyes like their mother, Cersei, despite the fact that their father, Robert Baratheon, has very dark brown (described as black) hair and eyes. While this in itself is possible, Ned reads through a book detailing Baratheon lineage and discovers that every dark-haired Baratheon male has always sired dark-haired children even if their mother was blonde. This would make it a lot less likely that Robert would be carrying recessive genes for blonde hair. Even without knowledge of genetics, this arouses suspicion, and is what leads Ned to the conclusion that Cersei's children are actually bastards born out of incest with her dirty blond-haired brother Jamie.
  • Justified in The Neighbors. The Bird-Kersee family consists of father - Larry (British, blond, and Caucasian), mother - Jackie (African-American), older son Reggie (Asian American), and younger son - Dick (Caucasian, american, and red-haired). They are all genetically related, though they are aliens from the planet Zabvron, and could choose their own human appearances. Funny though, because the parents and children don't see why they aren't seen as genetically related by strangers.
  • An example where family members are much too similar than is genetically plausible in Orphan Black: In the third episode, Cosima tells Sarah that clones' fingerprints may be close enough to all match, when in reality not even identical twins have the same fingerprints. Even accepting this premise leaves a Plot Hole, unfortunately. Beth's finger prints would have been put into the system when she became a police officer. If Sarah's arrest happened first, Beth would have had quite some difficulty getting into the police at all. If it happened second, the whole mess should have exploded then. Since only Sarah's fingerprints came up when Katja's were run, it must be that Beth's aren't in the system - presumably the showmakers don't know that police employees' fingerprints always go into the system. As for the "identical twins" part of things, averted entirely with Helena, who wore gloves when on the run to avoid getting fingerprinted.
  • In Power Rangers Mystic Force, Udonna, who looks Irish, has a son with Leanbow, who looks Spanish. The kid, Bowen, looks Arabian, with skin about eight shades darker than either of theirs— a shade fairly close to that of his parents' close friend Daggeron. No comment is made on this matter.
  • Reba
    • The redheaded title character and her blond ex-husband Brock have blonde Cheyenne, redheaded Kyra, Jake? In one episode it's stated that Brock dyes his hair, but it's not made clear if blond was his original color or not. Either way, it still wouldn't explain the vastly different hair colors that their kids have unless either Cheyenne or Jake dyes their hair too (Cheyenne was shown as a blond in a flashback to her first day of school and is unlikely to have dyed her hair at that age. This is the same reason why Jake probably doesn't dye his either.)
    • Adding to the confusion, Brock's other son Henry, whose mother is the very blond Barbra Jean, also has dark hair.
  • Roots's Chicken George is the son of Kunta Kinte's daughter Kizzy and her white slave master; he is one of the darkest characters in the series, significantly more so than his mother (and looks about the same age, though that's due to a different trope).
  • On Smallville, half-Dutch, half-Chinese Canadian Kristin Kreuk actress was cast as Lana Lang. Oddly, unlike their version of Pete Ross, there was no Race Lift involved—both her mother and father were portrayed by Caucasian actors. Potentially played with after the reveal that Lewis Lang isn't her biological father but then when she finds her bio-dad, he turns out to be white, too. Many viewers at first sight assume the WTH, Casting Agency? was involved.note 
  • Star Trek:
    • On Star Trek: The Next Generation, Wesley Crusher has brown eyes when both of his parents have blue. Picard, on the other hand, has brown eyes... However, while eye color is controlled by at least three genes and blue eyes mean you have to be recessive for all three, the color alleles are not completely dominant. It is possible for blue-eyed parents to have brown-eyed children.
    • On Star Trek: Enterprise, Archer decides to withhold a cure for a disease that's killing an entire race because it's their destiny as decided by their genes and they have to go to make room for another species. That's not even slightly how genetics works. There's no destiny, just a lot of essentially random events (this also overlaps with Goal-Oriented Evolution).
  • Sam and Dean Winchester from Supernatural resemble each other so little that not a single character on the show who doesn't already know even ventures a guess that they're brothers, and the majority of strangers think they're a gay couple. This is true even when they're pretending to be FBI agents or have some other plausible explanation for working so closely together.
  • Several on The Vampire Diaries:
    • Stefan and Damon sort of (if you squint) resemble their father, but the two brothers don't resemble each other at all.
    • Elena looks very different from her brother and aunt, but then it's revealed that she was adopted. Though it's later played straight when her birth parents were her father's brother John Gilbert and Isobel Flemming. While you could say she shares some of their facial features, there's no way two pale-skinned light-eyed people could have produced an olive-skinned child with dark brown eyes.
    • Elijah bears no resemblance to his family either, having much darker features overall. Ironic since Klaus, who does match the rest of the family, is supposed to be the illegitimate child.
  • Roseanne:
    • Lampshaded in a sadistic Halloween prank in an episode, where the dark-haired Roseanne and Dan had the dark-haired Darlene and D.J., but a blonde Becky (which isn't as unbelievable as some versions of this). When their snobby neighbor Kathy Bowman came over, she found Dan lying on the kitchen table, "gutted open" with assorted pieces of raw meat and fake blood sitting on his stomach. Roseanne walks in, covered in blood and holding a dripping knife, and she casually complains that she was so much better at this the last time. When Kathy asks what "last time," Roseanne casually says, "Becky's dad, he was blond, too."
    • Averted strongly with the casting of D.J. While neither Sara Gilbert (Darlene), Lecy Goranson or Sarah Chalke (Becky) bore a notable resemblance to their TV family, the main reason Roseanne Barr pushed for Michael Fishman to be cast was because he looked like he could be in her family, and even as an adult he looks like he could be one of her real children. He even played a younger Roseanne in flashbacks.
  • Good Luck Charlie: Parents Bob and Amy are blonde and blue-eyed, but their only blonde, blue-eyed kid is PJ. Gabe and Toby are dark-haired with brown eyes. While Teddy and Charlie are blonde, Teddy has brown eyes and Charlie's eyes are either brown or green.
  • Liv and Maddie: Both parents are brown-eyed brunettes and their son (Joey) looks like Robbie Shapiro (and Parker, also a brunette, is the Rooneys' answer to Ruthie Camden), so its very plausible that the two daughters are platinum blondes. Apparently the producers thought no one would notice. Blonde hair and green eyes are both recessive traits, so it is technically possible for the twins to have them though.
    • Played for laughs in how people are stunned to realize chubby redhead Artie and tall, handsome dark-haired Diggle are brothers. Artie not only assumes the resemblance is obvious but that he's more handsome than Diggle.
  • Yaphet Kotto was cast as Lt. Al Giardello on the award-winning cop series Homicide: Life on the Street, though his dark complexion and facial features made it very implausible for him to be the biracial son of an Italian-American father and an African-American mother. One episode of the series even went out of its way to draw attention to the issue when a light-skinned African-American woman declined to date Giardello because he was "too black" for her. That said, Kotto was outstanding in the role and it's impossible to imagine another actor playing Giardello. There is a valid argument for colorblind casting.note 
  • Although many of the families on 24 look related, a glaring example of this trope pops up in Season 4 with the Secretary of Defense and his daughter (played by William Devane and Kim Raver, respectively). To say they don't look alike understatement.
  • Life Unexpected: Lux lampshades how unlikely two brunettes having a blonde-haired child is in the second episode, where it turns out to be why she got her name (meaning "Light" in Latin). Interestingly, actress Britt Robertson, who plays her, isn't a real blonde anyway-her dark roots clearly show-and they could have just made Lux a brunette with dyed hair too.
  • Became a plot point in Arrow. When the cast was revealed, many cried foul at the fact that the dark-haired Willa Holland (Thea Queen) was supposed to be the daughter of two blonde parents (Thea's brother, Oliver, is played by the also-dark-haired Stephen Amell, but flashbacks have his hair much blonder and his present-day hair is cut so short it really doesn't matter.) However, a major plot development in the second season revealed that Thea is actually the illegitimate daughter of black-haired Malcolm Merlyn.
  • On Boy Meets World, most of the Matthews family look like they could be related, with the glaring exception of the main character Cory. He is played by the Jewish Ben Savage, who has dark curly hair, while the rest of the Matthews are played by WASPy-looking actors with wavy dark blonde hair. The contrast wasn't quite as obvious at the start of the series, but became quite a bit more noticeable after Ben/Cory went through puberty, where he became noticeably more Jewish-looking and even started affecting some stereotypical Jewish mannerisms. The hair inconsistency gets a reference at one point where it's mentioned that a babysitter once curled Cory's hair and it's been stuck that way ever since. The cast also joke about this at one point on the DVD commentary.
  • In the Hawaii Five-O episode "A Bullet For El Diablo," the daughter of a dictator is kidnapped as part of a plot to assassinate him - they'll substitute her twin half-sister, who's a member of the gang. Yes, El Diablo impregnated two completely different women who gave birth to females who look exactly alike. No, this isn't a science fiction story. And yes, the plan does work.
  • Played for laughs on Suits with Louis, a short man with a weasel-like face when his sister drops by, played by the gorgeous Amy Acker. People are stunned to see her and trying in vain to figure out how she and Louis could possibly be related. Even funnier? Louis assumes the shock is because "we could be twins."
  • It's Always Sunny in Philadelphia: Played for comedy and ultimately justified by the tall and slender Dennis and Dee having Danny Devito as their father. They eventually learn that he's not their biological father, to no one's surprise.
  • Twin Peaks: Brothers Ben and Jerry look nothing alike and have a foot of height difference between them. Given the weirdness of the rest of the show, this was probably intentional.
  • Still Standing: Lauren is a redhead, while her parents and siblings all have dark brown hair. This is somewhat plausible as her maternal grandmother is also a redhead.
  • Much like the Reba example above, 8 Simple Rules gives us blond-haired Bridget, red-haired Kerry and brunette Rory. Out of the three, Rory is the only one who looks like he could realistically be Paul and Cate Hennessy's (both brunettes) child. Cate's sister Maggie is also a blonde, further muddying the issue.
  • The George Lopez Show: Carmen is much lighter-skinned than her parents and brother due to her actress, Masiela Lusha, being Albanian. George is also far darker-skinned than all his family members, including both his parents. His mom is light enough to pass for Caucasian.
  • The Big Bang Theory: Penny is blond-haired, but both her parents note  are brunettes (her dad's hair is gray now, but Keith Carradine's hair was dark brown in his youth) and her brother has a lighter shade of brown hair. Penny's case may be justified, since a few episodes have implied that she is not a natural blonde. Still doesn't explain her brother, though.
  • The brunette Greg and Kim Warner of Yes, Dear have two blond-haired children, Sam and Emily.
  • Two and a Half Men
    • At least one episode ("Taterhead is Our Love Child") has pointed out how Jake looks nothing like Alan and, although unsaid, he really doesn't look like Judith either (for instance, both Alan and Judith have dark brown hair while Jake's hair is considerably lighter. Jake has blue eyes like Alan, but Judith's brown eyes should have been passed on to him). When Charlie and Alan drop Jake off at Judith's at the end of the episode, they see a plumber, a water boy, and a postman — all of whom look like Jake and are well-acquainted with Alan and Judith. Alan is oblivious.
    • Charlie and Alan are both brunettes, but their mother Evelyn has red hair. Either Evelyn isn't a natural redhead (it wouldn't be out-of-character for her to dye her hair, considering how she's always boasting about getting cosmetic procedures) or they take after their unseen father.
    • Charlie and Alan have the same hair color and that's it. Otherwise, they don't have any resemblance to each other (for one, Charlie Sheen has brown eyes and Jon Cryer has blue eyes, but it's difficult to tell this in a sitcom.) Much like the Winchesters, they are usually mistaken for a gay couple by those unfamiliar with them and even pretended to be one to impress a gay client of Charlie's.
    • None of Berta's relatives look anything alike. Berta's a redhead, her daughter Naomi is blonde and her sister, other daughter and granddaughter are brunettes. Then again, considering the implications of Berta's family, it could be justified, either due to hair dyeing or illegitimacy.
  • In Teen Wolf, redhead Victoria Argent and dark blond Chris Argent were both blue-eyed and had straight hair. Their daughter, Allison, had dark brown eyes and either dark brown or black hair that was naturally a bit wavy when she had it long. There were fandom theories that Allison might actually be the biological daughter of her aunt, Kate, and a member of the Hale family. After she had her hair lightened, she did show a slightly stronger resemblance to her aunt than she did previously. Kate was blonde with somewhat wavy hair and green eyes, and all the Hales shown had either black or dark brown straight hair and a combination of blue, green, and brown eyes. Kate and Chris' father, Gerard, had blue eyes, but it's not clear what color his hair was before it turned white-gray and he started balding. A flashback did show a brown-haired Argent with brown eyes, however, and he might have been Gerard's brother, although all that's said is he was Chris' uncle. Given the fact the Hales were supernatural and Allison started having precognitive hallucinations, this only added to the theory that, at least, one of her parents might not be a biological one.
  • iCarly:
    • Sam Puckett is played by the 5'2" Jennette McCurdy. Her mother, Pam, is played by 6' Jane Lynch. Though to be fair, Pam only showed up in one episode after spending four years as The Ghost.
    • Freddie is also much shorter than his mother.
  • During the mid-90's, General Hospital brothers AJ and Jason were respectively played by Sean Kanan and Steve Burton, who were often said to resemble each other more than real brothers do (the two were cousins in Real Life). However, the two were half brothers, which meant there ought to have been more differences in their appearances, and even if one could assume that they both happened to take after their father Alan, he was dark haired and dark-eyed, the complete opposite of them—they resembled their mother Monica far more even though Jason wasn't her biological child!
  • In the Law & Order episode "Blood", the detectives are stunned to learn that their suspect is actually a black man passing for white when they see the baby that he forced his wife to give up for adoption. Despite the roulette game that is genetics, it's highly unlikely that a white person and an African-American so light he could pass for white (and therefore highly likely to have white ancestry himself) could have produced a child with such a dark complexion.
  • The Bold and the Beautiful. Stephanie Forrester is dark-haired and dark-eyed while her twin sister Phoebe was the polar opposite—blonde and blue-eyed. While fraternal twins often look different, it's still odd that Steffy would so closely resemble their parents Ridge and Taylor while Phoebe didn't.
  • Almost Family: Edie's mother (who's played by Tamara Tunie) is lighter-skinned than she is. Her birth father turns out to be white though, which is genetically quite unlikely.
  • How to Get Away with Murder: Laurel and Adrian are much lighter than their father. While it's possible one might have their mother's fair looks, two is pretty unlikely given dominant traits of darker hair or skin.
  • Vikings: Bjorn, Ragnar's son from his short-statured wife Lagertha, is quite a bit taller than all of Ragnar's sons from the Statuesque Stunner Aslaug.
  • The Sopranos: Meadow has a noticeably darker complexion than everyone else in her family. The actress is actually half Cuban and half Ashkenazi Jew rather than Italian-American. This gets brought up in dialogue in the fifth season, when Carmela recalls how her mother lamented "She's so dark!" when she first saw her granddaughter.
  • Succession: The short, stocky, bulldog-faced Brian Cox and the tall, lanky, aquiline James Cromwell could hardly look more dissimilar, but they play brothers.

  • In many stage shows, the producers will choose Ability over Appearance and cast vastly physically different actors as relatives. Not to mention if you're in the back row of the top balcony you probably won't notice if Hamlet has green eyes and Gertrude has brown.

    Video Games 
  • Gaia Online, otherwise pretty good about NPC hair colors, retconned Ian into being a vampire in '07, around the time his father Vladimir was introduced (and killed). Ian's hair has since been recolored black, which he says is his natural color. The problem? Vlad has been confirmed as having dark brown, possibly even auburn, hair, and Ian's late mother Rosalie was a blonde. Despite this, it appears black in the manga, so it could be a retcon.
  • Xenogears plays with this—because both of her parents are blond (as is everyone else on the Floating Continent Solaris) and she's a redhead, Elly feels like a literal Red-Headed Stepchild to her mother, thinking that her real mother was her red-haired nanny. However, this is both plausible (the way red hair works genetically allows for blonds to be recessive for it) and a moot point anyway, since the reason she looks like she does is because she is a Reincarnation of The Anti-Type.
  • Played oh-so-straight in Solatorobo, where not only can vastly different races within the species breed freely (foxes with wolves and housecats with lions, for example), but Caninu and Felineko can have children with no problems as well. To top off the Hollywood Genetics, their offspring will be either Caninu or Felineko, not some sort of dog-cat hybrid.
  • Pokémon Black and White: Cilan, Chili, and Cress are triplets with different hair and eye colors. Bonus points for each of them having their hair and eyes match each other AND their specialty Type all in one.
  • Harvest Moon 64: Karen is the only girl who has less than a passing resemblance to her implied grandmother, in her case Eve from Harvest Moon. The only resemblance is that Eve had blonde hair while Karen has blonde... bangs. Her cousin Cliff also inherited blond bangs from Eve.
  • Blonde-haired, blue-eyed Ann Takamaki from Persona 5 is mentioned to only be one-quarter Caucasian American, with the remaining three quarters being ethnically Japanese. It's very unlikely for someone like Ann to look the way she does even if she were half-Caucasian, let alone a quarter. While she's mostly the way she is as a deliberate design choice in order to emphasize her status as an outcast, it's still pretty bad. This is especially considering that Persona 2: Innocent Sin actually featured a blonde-haired, blue-eyed playable character (Lisa Silverman) who not only actually was fully Caucasian, but also had a backstory that neatly deconstructed and examined life for an "exotic"-looking person raised in a monoethnic society; Ann's own history is barely mentioned again after the first arc of her game.
  • Dixie Kong and Tiny Kong from the Donkey Kong universe are sisters. They both have similar fur tones and blonde hair however Tiny is bipedal and fully clothed while Dixie is less anthropomorphic looking, walking on all fours and being a Half-Dressed Cartoon Animal. The difference in looks became even more noticeable when Tiny was aged up. Tiny is a tall, Humanoid Female Animal while Dixie more resembles Diddy.
  • The Last of Us: Joel has black hair, while his daughter Sarah is a blonde. She could take after her Missing Mom, but even then, Sarah being a blond is unlikely.
  • Metal Gear Solid: Snake and fellow Big Boss clone Liquid are not ordinary clones; the scientists who created them caused the dominant genes to be expressed in Snake, while Liquid expresses the recessive genes. Liquid, with a supposed IQ of 180, states that this means Liquid's genes are flawed. Snake, also with an IQ of 180, apparently does not see the problem with this. "Dominant" and "recessive" are value-neutral descriptions for genes. It simply means that if you have a dominant gene paired with a recessive, the former is the one whose trait will manifest in you. In the post-credits one-sided phone call, it's stated that Snake was actually the inferior one, so maybe the writers understood the genetics, or maybe they meant that Snake was the one with the recessive genes.
  • NBA 2K16's story mode, Livin' Da Dream, features the story of a player created character nicknamed Frequency Vibrations. Freq's race is customizable by the player, but his parents are both African-American, and Freq's mother mentions that she came up with the name while pregnant with him, discrediting the idea Freq was adopted. The implications of this are never brought up in story.

  • Invoked via the musical example in Kevin & Kell, where in a production of West Habitat Story Fiona, a fox, is cast as Maria, while Rudy, a wolf, is cast as Maria's brother. Granted, Rudy does have some fox ancestry in him but he looks and identifies as a wolf. And it becomes moot when he's recast as Maria's would-be fiancé anyway.
  • In Savestate, Kade and Nicole are blue merle and red merle (respectively) Australian shepherds. Their mother is a blue merle, like Kade. The author has said that their father, who has yet to be introduced, is a standard red, thus averting this trope as far as they are concerned. If both parents were merles, the result in reality would likely be a very rare and problematic double-recessive genetic combination called a white Australian shepherd, which is susceptible to genetic defects involving their eyes and ears.
  • In Alice and the Nightmare, a child of two different Suits (races/castes) will only inherit a Suit of one of their parents, and there's no dominant or recessive Suit. That's why, for example, it's impossible to guess that Dee, Dum and Edith are actually siblings, as they look completely different.
  • In Arthur, King of Time and Space Arthur and his son Mordred are both brunettes in every timeline, though the identity of Mordred's mother varies. In the baseline and space arcs his mothers are Arthur's black-haired half-sisters Morgause and Morgan, respectively, which would require either of them to have a recessive gene. While in the modern-day arc Mordred was born to Guinevere, a redhead, and his younger brother Galahad has black hair, like Lancelot.

    Western Animation 
  • The Adventures of Jimmy Neutron: Boy Genius: Cindy Vortex is a green-eyed blonde. Cindy's father has brown hair and brown eyes and while Cindy's mother has green eyes like her daughter, her hair is black. Many fans believe Cindy to be adopted due to this lack of resemblance and it's even brought up a time or two in the show itself.
  • Tony and Megan from The Amazing Spiez are Ambiguously Brown, while neither their parents nor other siblings are.
  • In the American Dad! episode "The Kidney Stays In The Picture", it is revealed that Francine slept with another man right before her and Stan's wedding, meaning Hayley may not be his biological daughter. Francine is a brunette who dyes her hair blonde. Stan and Hayley both have black hair. The man Francine slept with had brown hair. The one thing Hayley and him have in common? A bandana. The funny thing is that many viewers would have thought their son Steve would have a different father, due to him having brown hair, but even if Francine was a natural blonde, such an outcome is far from unlikely.
  • Arthur: In "Arthur's Cousin Catastrophe", one of Arthur's cousins, Ricky, is significantly darker than his parents and siblings. He also has dark, curly hair, unlike his straight-haired family. His design was later changed in "Dancing Fools", making him lighter furred like the rest of his family.
  • In Batman Beyond, Terry's parents are both redheads (his dad being more of an auburn shade), Terry and his little brother had black hair. In the Distant Finale which was also a Fully Absorbed Finale (the Justice League Unlimited episode "Epilogue") it was revealed that Bruce Wayne is Terry's biological father by way of Cadmus mad science, fixing the whole mess. Apparently an Author's Saving Throw as a solution to people noting its impossibility (it also helps that Terry's parents already had marital issues that suspected infidelity could have contributed to). Note that it never occurred to anyone to simply suggest that one of them dyes their hair...
  • From Danny Phantom Sam Manson has black hair while her father and mother have blond hair and red hair respectively. Someone in the family probably dyes their hair. Given the fact that Sam's a Goth, it's most likely her.
  • The Lane family of Daria all have blue eyes except for Trent, whose eyes are black.
  • Family Guy has brown-haired Fat Idiot Bumbling Dad Peter and red-haired Lois. Their children are brown-haired Butt-Monkey Meg and Brainy Baby Stewie (Stewie Griffin: the Untold Story confirms this) and blond Chris. In and of itself, this is reasonable; Peter could have a recessive blond gene (which will dominate the red). However then we get Bertram, the kids' half-brother on their father's side. He has red hair, even as a sperm cell. Peter's biological father is red-headed, so he is definitely carrying the genes of red hair for Bertram to inherit, but it's very unlikely that he's masking blond hair, too. The fact that Lois is redheaded means that she most likely only has genes for red hair, so barring a mutation, it can't come from her, either.
    • Chris' hair is a leftover from the original pilot, where Lois was a blonde and Chris inherited her hair color. The actual show changed her hair red without changing Chris' hair.
  • Hey Arnold! Gerald, his parents, and his older brother are all medium-skinned African-Americans. His younger sister, is light-skinned. Perhaps the crew caught on, since Hey Arnold! The Jungle Movie shows her (as a background character) with a skin color closer to that of the rest of her family.
  • On The Jetsons, George and Jane Jetson are both redheads, yet their children Judy and Elroy are both blonde (Judy's being platinum, to be specific).
  • In the My Little Pony: Friendship Is Magic episode "Baby Cakes", Mr. and Mrs. Cake (both earth ponies) have twins, who are a pegasus and a unicorn. Mr. Cake hastily explains that he has a unicorn ancestor, and Mrs. Cake has a pegasus ancestor, then sheepishly adds "That makes sense, right?" While the girl (the unicorn) has the same coloration as Mr. Cake at least, the boy has a completely different color pelt, mane, and eyes. What really drives the trope home: Mrs. Cake's pegasus ancestor was her great-aunt's second cousin twice-removed. Mrs. Cake does not actually share any DNA with this pegasus, yet she somehow passed it on to her son.
    • While it is played for laughs in the episode, there isn't ever any clear statement of how pony genetics work. Despite the variable number of limbs, they are all a single species. The existence of Cloudsdale indicates that you don't have surprise non-Pegasi births (as the city is made of clouds, any non-pegasus will fall through the floor), so it's likely a recessive gene.
  • South Park:
    • Kenny is blond, his parents have brown hair (his father) and red hair (his mother), and his older brother and younger sister also have brown hair. The reason could be some people have blond hair as children and light brown hair as adults, but as stated before, Karen already has brown hair.
    • Craig has black hair, but his father is a redhead and his mother is a blonde. Though if the blowup-doll replica of his mother and her bush is accurate, she's probably not a natural blonde.
    • A lampshaded case, which currently provides the page image, happens in the episode "Ginger Kids". Stan and Kyle visit the home of three ginger kids and discover that the kids' parents are brunettes. The couple explains that they both had recessive genes for red hair and that's why their kids look the way they donote , though they seem quite disappointed about that.
  • Young Justice:
    • The Dark Skinned Blonds teenage superheroine Artemis is the biracial daughter of blond, Caucasian supervillain Sportsmaster and the Vietnamese-American reformed supervillainess Huntress. While not outright impossible (such as if there was a blond, Caucasian ancestor on her mother's side, which could happen since Vietnam is a former French colony) Artemis' hair colour is, at best, unlikely. She's actually based on the daughter of one of the show's producers who is half-Korean on both sides (both parents are mixed race) and a natural blonde.
    • Cheshire herself has a child by the timeskip in season two. Lian is Roy's daughter and inherited his red hair color. She mixes her original comic design (which took completely after her father) with her more well-known redesigned look (which looks more like her mother). As with Artemis, it's justified in that Cheshire is multiracial, being Artemis' sister.
  • The Simpsons: Homer (had brown hair before he went bald) and Marge (blue hair) have three blonde kids. None of the Bouviers are blonde, and Abe Simpson also had brown hair... One episode claims that Bart's natural hair color is red which makes it weirder.
  • Major characters in Jem have naturally technicolor hair but more minor characters don't. This extends even to parents, which causes this:
    • Kimber and Jerrica are two of the very few main characters who have both biological parents shown. Jerrica is near identical to their blonde mother but Kimber, with her pinkish-red hair, doesn't resemble either her father or mother. Her father has reddish hair, but not in the same tone as Kimber.
    • Raya's entire family has black hair except for her. She has pink hair and, according to a childhood flashback, it is likely natural.
    • The Dark-Skinned Blond Riot has parents who are lighter skinned and have brown hair. According to "Riot's Hope", his skin and hair color are natural.
    • Purple-haired Clash has a reddish haired father.
  • Caillou: Caillou's dad has brown hair, and his mom has black hair. His little sister...has red hair.
  • Big City Greens: Tilly has black hair, despite her dad, brother, and grandmother having brown hair (though the grandmother's hair is grey now), and her mother being a redhead. However, an episode covering the Greens' family history shows some of the Green ancestors have a strong resemblance to Tilly.
    • Tilly's grandfather has black hair, suggesting he passed the gene down through Bill to Tilly.
  • King of the Hill
    • The brown-haired Hank and Peggy have a blond-haired son Bobby. Their parents also had brown hair in their youth but it's implied it comes from Hank's side of the family as Hank's half-brother that Cotton fathered from his second wife Didi looks identical to Bobby blond hair and all.
    • Turns out that Hank has another half-brother named Junichiro, who was the result of Cotton's relationship with his Japanese nurse following WWII. Junichiro looks exactly like an Asian version of Hank, even though Hank gets his looks from his mother Tilly, who is of no relation to Junichiro.
  • In Infinity Train, the redheaded Tulip has a blonde mother and a brunet father.
  • Dave the Barbarian: Dave has brown hair. His father and sisters are redheads and his Ambiguously Brown mother has pink hair (Dave, Fang, and Candy all have tanned skin to reflect their mother's ancestry, however).
  • Miraculous Ladybug: Main character Marinette has blue eyes, while her parents have grey and hazel eyes.
  • Kick Buttowski: Suburban Daredevil: The titular character's father, Harold, has dark brown hair while his mother, Honey, is a redhead. His siblings, Brad and Brianna, have black and blonde hair respectively. Harold could be hiding a gene for either of those shades, but not both and Honey would only have red hair genes.


How well does it match the trope?
