* Due to some weird goings on with the X chromosomes (if two dominant coat genes show up on different X's, they both show up on the cat), it is impossible to have a male calico cat, because males only have one X chromosome.
** Technically speaking, it's possible to have a male calico/tortoiseshell cat so long as the cat has two X chromosomes ''and'' a Y. Which does happen, as a genetic defect (a fairly harmless one, as these things go). It's just that it's extremely rare for an XXY cat to also have tortoiseshell genes.
*** And because of the extra X chromosome, male calico/tortoiseshell cats are sterile.

** Where in the film does it say that they aren't? They could just be examples of BizarreSexualDimorphism; with feline females and canine males.

* {{Pokemon}} subverts this. The child of two different Pokémon will always be the same species as the mother. Although if either parent is Ditto, the child will be the non-Ditto parent. For male-only species, such as Tauros and Hitmontop, they can only reproduce their own species by breeding with Ditto. This is justified, as all Pokémon species draw from the same gene pool, and are actually subspecies.

* [[http://www.youtube.com/watch?v=cZrkp2La3FA&feature=channel In this Japanese commercial]] for the heavily advertised {{Solatorobo}}(a mecha game feature anthro characters), this trope is illustrated at first between an interspecies couple and then subverted when a hybrid is shown! Here’s to hoping [[HotSkittyOnWailordAction Cheetahs and Bulldogs]] never mate.

* Perhaps due to the popularity of this trope in entertainment, many children (including this troper and, decades earlier, her mother) mistakenly assume that cats and dogs are the same species, with cats as the mothers and dogs as the fathers.

* At the end of LadyAndTheTramp, their puppies are three girls who are pure-bred cockers like Lady, and the boy Scamp who looks just as much a lovable mongrel as his father.
* In ''TreasurePlanet'', the children of [[spoiler: Delbert and Amelia]] display this. The three girls are clearly modeled after their mother and the boy is clearly modeled after his father.

* ''GoofTroop'': Pete and Peg's children. P.J. looks like Pete, and their daughter Pistol looks like Peg.

* Played with in ''RockosModernLife'', where the children of Philbert and his wife are all male turtles and female cats... And one steer who resembles Heifer, which raises [[GettingCrapPastTheRadar all]] [[YourCheatingHeart sorts]] of [[VoodooShark questions]]. ([[DontExplainTheJoke Steers are castrated.]])

* Perhaps due to the popularity of this trope in entertainment, many children, including this troper and, decades earlier, her mother, mistakenly assume that cats and dogs are the same species, with cats as the mothers and dogs as the fathers.

Compare with the BizarreSexualDimorphism, where a single species has very different-looking genders.

* {{Pokemon}} subverts this. The child of two different Pokémon will always be the same species as the mother. Although if either parent is Ditto, the child will be the non-Ditto parent. For male-only species, such as Tauros and Hitmontop, they can only reproduce their own species by breeding with Ditto.

*** The same goes for Changelings. As changelings can breed with any race thanks to their shapeshifting, the resulting child will have the same race as the parent of the same gender. Also note that changelings CAN change their own gender (though if impregnated they will remain locked as females until they give birth).

* In ''GoofTroop'' Pete is a cat, and his wife Peg is ... [[FurryConfusion probably a dog]]. Their son P.J. looks like Pete, and their daughter Pistol looks like Peg.

** While the Gerudo and the Hylians seem to apparently believe this is how it works, based on their dialogue, if you look deeper, it's actually averted. It's implied that Malon, a redheaded Hylian girl, is the daughter of a Gerudo and a Hylian.

It should be noted in male / female same species examples given here that it ''is'' possible for traits to be sex linked. Since human females have two X chromosomes and males have one X and one Y (usually; there are cases where it is not so clear), diseases or other things can be restricted to one sex. One example is color blindness, about 5?8 percent of males, but less than 1 percent of females, are color blind in some way or another.

* Used in the third issue of the Spanish-for-a-French-market comic {{Blacksad}}, the chief of police is characterized as a German Shepherd, his wife is some sort of spaniel. Their son is also a German Shepherd, and their daughter the same spaniel breed as her mother.

* In TheBelgariad, dryads are a OneGenderRace. Dryads kidnap human males for [[strike:re]]procreational purposes, after which they are killed, along with any male offspring. Females are apparently full dryads.

* This concept is parodied and then subverted in Scrubs when the AlmightyJanitor fantasizes about being married to Elliot. They are surrounded by little girls dressed as doctors like Elliot 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.

* In the TabletopGames ''Castle Falkenstein'', [[OneGenderRace there are only male dwarves and female fairies]]. The solution? Dwarves and fairies can mate - male offspring always become dwarves, females fairies.

* Lampshaded in ''Knights of the Old Republic 2'', with a Human sub-species or variant species that ''specifically'' works this way, the Echani. The somewhat creepy Echani Handmaidens all look identical because Echani always physically take after the parent of the same gender. The one exception is a pariah because the fact that she looks different is a sign of their father's infidelity -- and because she looks exactly identical to her mother at her age. The creepiness is enhanced by [[spoiler:the credible fan theory that the Handmaiden's mother is Kreia]].

* In TheElderScrolls game series, the race of the child is determined almost entirely by the mother, with few of the father's racial traits making it through with certain, important exceptions.
* The ending of {{Grandia}} shows Justin and Feena several years later, married, with a bunch of little-Justins and little-Feenas running around.
* The Gerudo from LegendOfZelda Ocarina of Time... maybe. The Gerudo are an all-female tribe of desert bandits that produces a male every one hundred years. In order to procreate, they visit Castle Town to meet Hylian "boyfriends". 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.

* The animated film ''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.

* In the Dungeons and Dragons campaign setting of {{Eberron}} uses this to escape having to make stats for half-Kalashtar. [[JustifiedTrope Justified]] by the spirits which define a Kalashtar bloodline having clearly defined genders.
** The same goes for Changelings. As changelings can breed with any race thanks to their shapeshifting, the resulting child will have the same race as the parent of the same gender. Also note that changelings CAN change their own gender (though if impregnated they will remain locked as females until they give birth).
* In the Tormenta setting for Dungeons and Dragons, minotaurs are a playable race with their own nation inspired on Rome. There are no female minotaurs. They mate with humans(generally their slaves) or Half-Elves, and the males are minotaurs, while the females are from their mother's race.

* ''Muppet Christmas Carol'': Kermit and Piggy's children are male frogs and female piglets.

* Used in the third issue of the Spanish-for-a-French-market comic {{Blacksad}}, the chief of police is characterized as a German Shepard, his wife is some sort of spaniel. Their son is also a German Shepard, and their daughter the same spaniel breed as her mother.

* Lampshaded in ''The Class Menagerie'' web-comic, where gender and species are explained as being based on that of the parents.
