The naming of hybrid animals depends on the sex and species of the parents. The father giving the first half of his species' name and the mother the second half of hers. (I.e. a pizzly bear has a polar bear father and grizzly bear mother whereas a grolar bear's parents would be reversed.)
Subsequent generations may see a purebred animal crossed back on a crossbred, creating a 75/25 cross, [7] or a BC1 or F1b "backcross." [citation needed] The breeding of two crossbreeds of the same combination of breeds, creating an F2 cross, an animal that is still a 50–50 cross, but it is the second filial generation of the combination.

The humanzee (sometimes chuman, manpanzee or chumanzee) is a hypothetical hybrid of chimpanzee and human, thus a form of human–animal hybrid.Serious attempts to create such a hybrid were made by Soviet biologist Ilya Ivanovich Ivanov in the 1920s, [1] and possibly by researchers in China in the 1960s, though neither succeeded.
Animals only rarely exhibit inbreeding avoidance. [1] The inbreeding avoidance hypothesis posits that certain mechanisms develop within a species, or within a given population of a species, as a result of assortative mating and natural and sexual selection , in order to prevent breeding among related individuals.
A mule is a sterile hybrid of a male donkey and a female horse.Mules are smaller than horses but stronger than donkeys, making them useful as pack animals.. In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction.
A felid hybrid is any of a number of hybrids between various species of the cat family, Felidae. This article deals with hybrids between the species of the subfamily Felinae ( feline hybrids ). For hybrids between two species of the genus Panthera (lions, tigers, jaguars, and leopards), see Panthera hybrid .
Hybrid speciation in animals is primarily homoploid. While thought not to be very common, a few animal species are the result of hybridization, mostly insects such as tephritid fruitflies that inhabit Lonicera plants [20] and Heliconius butterflies, [21] [22] as well as some fish, [15] one marine mammal, the clymene dolphin, [23] a few birds.
Technically, in a human–animal hybrid, each cell has both human and non-human genetic material. It is in contrast to an individual where some cells are human and some are derived from a different organism, called a human-animal chimera. [1] (A human chimera, on the other hand, consists only of human cells, from different zygotes.)
