I am not going to say that she isnt, but I feel it is a better chance that it was just a coincidence. I dont know what her parents were either. I did have a female black pastel go 6 fer 7 on passing genes on, so it could just be dumb luck (if I have luck it is dumb) I will be breeding the same female to a butter as long as he decides to breed this year, if she goes 100% 2 years in a row I will start wondering.
