Not all of them. You can now buy short tailed kitties with bobcat or lynx ancestry. I haven't seen any coydogs offered for sale but it is not hard to produce them. Wolfdogs are pretty common, though of course, the dog is currently classified as a subspecies of wolf.

Even intergeneric crosses with fertile offspring.

The same problems occurred in the production of beefalo. Of course all the poor quality animals were sent to the slaughterhouse and only the better ones were kept as breeding stock. It took probably about half a century to make a breed competitive with herfords and angus.
People don't generally eat baby snakes, of course, but other snakes do. I have about 20 Iowa ratsnake X Everglades ratsnake
babies. I don't intend to sell any of them. Except for 2 males and 3 females I will be keeping to interbreed for an F2, they'll go to feed my blue racer. If I'm lucky, some of the F2 will be beautiful orange with black splotches and no stripes. Anything that does not look marketable will be snake food.

Which is why people should be breeding with the intention of producing fully domesticated animals that are comfortable in a variety of environments, preferably one that will eat processed food so that people who are squeamish about feeding them animals will be willing to keep them as pets.

Um, those are the same problems wild snakes have. One of my friends was foolish enough to put a boa in the same cage with a much smaller eastern king. Oops, one dead boa.

There you have a point. You don't have to worry about me doing that. Poisonous snakes scare the bejesus out of me.

In any plant/animal breeding operation, one simply is not going to get all high quality products even when breeding within species. The inferior organisms are culled. At least culled snakes can be used towards reducing operating costs. What do you do with a unsalable great dane pup with hip dysplasia?

That's where we need to breed snakes of sufficiently high market value that only the more serious pet owner will buy them.

There certainly are. And people who raise those species for sale should a) be capable of providing pedigrees to prospective buyers so as to ensure the animal bought is a pure species, and b) provide husbandry info. A blue racer, for instance, can live a long life in captivity but will most likely die if the owner does know know its specific needs.

There certainly is a lot of information that would be useful in understanding genetic mechanisms and evolution.
Thats my 2 cts-and as a biologist, I have done my homework concerning the health risks of hybridization!
Have you done your homework concerning the health risks of inbreeding pure species?
