I agree with Deborah, apples and oranges. With out " line breeding" we would have a much harder time proving out morphs. With out this natural "inbreeding" we would not have the any local specific animals. breeders have been doing it for years. this is also why we have blood line specific bp morphs. What breeders are doing with line breeding is not something un natural in it self, it's more at the pace in with it is done. We are talking about an animal that can produce viable eggs with out ever being introduced to a male. Now that's inbreeding
