I like this. I think it's crucial to how one thinks about all this. How exactly is that done? Remove the animal expressing the "bad" gene and possibly it's parents from the line? (Sorry, I know that's getting pretty off topic.) This is something I've never really understood. And won't the line still suffer from lack of "hybrid vigor"?
