Breeding in the species...

[FWK]

I should clarify a bit. The animal you suggested in your original question, Sonoran Gopher X Bull Snake, both being subspecies of the same species, would not actually be a hybrid but an intergrade. This intergrade is very common naturally as the ranges of these two subspecies border each other over some 1100 miles from northern New Mexico, through Texas, and into Mexico. Offspring of subspecies of the same species are known as intergrades, offspring of two different species are hybrids. Sorry I got carried away with the hybrid thing and didn't really clarify the answer to your original question.

Thanks very much, this is the exact info I was looking for!
