guess gonna have to gosh fudge it, I'm curious now I mean if it's a sex linked gene you'd think it would beable to pass the gene on right?Not that I have seen.
But then I have not tried to do so !
IF you want to cross a breed, and follow it through from gen to gen, to develop a new variation, then maybe, maybe not ?
What you'd need to do is study & maybe contact ppl that raise that particular variation of that particular breed.
