Interspecies hybrids: natural & artificial

[brotherbear]

I can't add much useful information about the breeding of Barren ground grizzlies and polar bears, other than from what reading I've done, I have learned that the mixing of the two species is a very rare event but nothing new. Grizzly bears have been breeding with polar bears for thousands of years, but again, only in rare events. One thing that I have not read about, is it always a male grizzly and a young female polar bear, or do male polar bears mate with female grizzly bears as well? Reply
