Yes, and a domestic dog could survive and breed in the wild as well.

Are all domestic corns identical in every way to wild corn snakes of a given locality? Given that many different localities are breed together to achieve various morphs... I'd say there is some variance as breeders do not always simply breed one locality to a member of the same locality. Are different localities or rare new morphs not breed to other morphs that may have appeared in another corn snake from a completely different local? This would not happen in nature. Have hybrids already mixed or intergrades already been selected for and parentage lost in such a manner as to leave some corn snakes at least with a questionable heritage? I would say change of diet, temperament, color.... or simply breeding locals together that would never occur on their own in the wild if not introduced by man to be significant changes. I'll agree we have come much further with the dog, but what has been done with the corn snake is no small achievement either. Whether a domesticated animal or an animal that man has selectively bred for traits and whether that animal can exist on its own in nature if released.... interesting point your trying to make there as well. Many animals selectively bred by man can breed with their wild counterparts. Turkeys come to mind as one such example. Of course, some breeds bred by man can no longer reproduce naturally at all.
