Genetic analysis has revealed multiple instances of introgressive hybridization between bear species, [4] [5] [6] including introgression of polar bear DNA into brown bears during the Pleistocene ("grizzly bear" is a local common name for Ursus arctos whereas "brown bear" is used internationally and in science to refer to the species as a whole).
Ligers and tigons (crosses between a lion and a tiger) and other Panthera hybrids such as the lijagulep. Species P. tigris. A hybrid between a Bengal tiger and a Siberian tiger is an example of an intra-specific hybrid. Family Canidae. Fertile canid hybrids occur between coyotes, wolves, dingoes, jackals and domestic dogs.
Possible hybridisation between different species of bear. An ursid hybrid is an animal with parents from two different species or subspecies of the bear family (Ursidae).Species and subspecies of bear known to have produced offspring with another bear species or subspecies include American black bears, grizzly bears, and polar bears, all of which are members of the genus Ursus.
Panthera hybrids are typically given a portmanteau name, varying by which species is the sire (male parent) and which is the dam (female parent). For example, a hybrid between a lion and a tigress is a liger, because the lion is the male parent and the tigress is the female parent.
Like white tigers and black tigers, it is a morph, and not a separate subspecies. Known for its blonde or pale-golden color and red-brown (not black) stripes, the golden tiger colouring comes from a recessive trait referred to as "wideband" which affects the production of black during the hair growth cycle.

It typically results from hybridization with non-native species, leading to decreased variation in the gene pool. [4] These hybridization events may be either interspecific or intraspecific. [1] Genetic homogenization can be analyzed in terms of allelic frequencies, which is accomplished through a comparison of how common specific genotypes are.
In theory, white tigers could be crossed with white lions to produce white, very pale or even stripeless ligers. There are no black ligers. There are no black ligers. Very few melanistic tigers have ever been recorded, most being due to excessive markings (pseudo-melanism or abundism ) rather than true melanism; no reports of black lions have ...
Hybridization was one way rapid changes in an organism's genetic makeup could be introduced. Crop hybridization most likely first occurred when humans began growing genetically distinct individuals of related species in close proximity.
