Misplaced Pages

This is a list of genetic hybrids which is limited to well documented cases of animals of differing species able to create hybrid offspring which may or may not be infertile.

Hybrids should not be confused with genetic chimeras, such as that between sheep and goat known as the geep. Wider interspecific hybrids can be made via in vitro fertilization or somatic hybridization; however, the resulting cells are not able to develop into a full organism.

Nomenclature

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.)
