Thank you Red for clarifying, I think we are being curious about exactly the same thing.
Kathy thank you for all the explanations regarding genetics, I truly appreciate it, you clearly know much about the mechanics of genetics. I think we all agree that a mutation happened and I don't think we are that concerned on how the mutation happens, i.e. the genetic mechanics of it, but rather, moving beyond the mechanics, why (if location is irrelevant) it seems to be happening in the US only, and if it started with one individual that then spread it around or if it is continually happening.
I also think it is a little bit confusing to say the trait is inheritable but then say cross-breeding has nothing to do with it. Clearly, cross-breeding has everything to do with introducing new genetic material into a breed, including mutated genes, if they are not already there. I am interested in knowing how cross-breeding has been ruled out definitively.
Does anyone have answers to these questions?
