There is a very loose dominance hierarchy within bear mating systems due to their solitary nature.

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.
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.)
