I was recently given a decent rex doe that was passed on getting culled due to the fact she was nice in many ways, but for lack of a butterfly on her nose. If I breed her to a solid buck will she possibly pass kits with butterflies or no. I read an interesting article about this problem being more common in broken chocolates/choc otters by one breeder. I can breed her to my black buck if that would increase the odds of better color. What are your experinces. While I will cull for meat, I don't breed specifically for this reason myself, so won't breed her if there is no chance.
