"Look at any, and I mean ANY pet store. 99.9% of the snakes sold there are hybrids."

But most of that is due to secretly breeding morph genes of one species into other species and then backcrossing so it looks like the species they want. These crosses do look good and make good pets, etc. but most people who buy them are under the impression that they are buying a pure snake.
