It doesn't make a difference.

Which was the point of my post. It's a chance regardless of what fur or whisker, or whichever trait is showing. And you don't "lose" traits in breeding. If you have 120 days to breed a kitten, and not one of the offspring shows or hides the recessive trait...I'd consider this person extremely unlucky, but I also backbreed all of my new, recessive traits. Perhaps that is the difference?
