k, genetically speaking. . . do you think there's that much difference between the two (old and new) that they wont have viable young. I'm being sincere. If you can breed a king corn cross, then there must be decent odds that you can breed a pantherophis guttata with a elaphe. . . considereing they are ancestors of each other. . . i understand the difference between the two, but I know that parrot fish are a cross between two genus and they are possible. Although the males are believed to be infertile. Can there really be that much difference between the two. In my view, the only difference is location. I might be naive, but I still think it's possible, but I don't want to create a franken-snake either. I would feel horrible if I tried it, and something bad happened. Do you know the reason that new world was reclassified. . . was it genetic differences, or just the difference between here and there? I really would like to discuss this at length if anyone cares to.If I do still try to breed it will be with Elaphe Prasina
