Biology 20 Help Please!!! Inter-genus breeding?

Question

Bear populations are scattered across the northern hemisphere in temperate, boreal and arctic/alpine regions.

The Panda bear of China has the taxonomic names Family Ursidae and genus species Ailuropoda melanoleuca which means "cat feet or panda footed; black and white."

The grizzly bear of Jasper National Park, AB., has the taxonomic name Family Ursidae and the genus species name Ursus horribilis.

Is it possible for these two bears to mate and produce future generations?

Answer 1

It is extremely unlikely to occur in nature.  The biological definition of species is whether two individuals can reproduce and produce viable offspring that are themselves able to reproduce.  The panda and grizzly are not just different species; they are different genera.  

It might be possible if gametes were extracted from both and manipulated in the lab, and then one of the females of one of the species were used as a surrogate mother to implant any fertllized eggs that resulted.
