So I was reading the thread on blue eyes and how they are inherited and it made me want to ask this question I have been wondering about.
How is it that some sabinos are heavily roaned and others are not? Is it a different form of sabino or what?
I was talking to a friend about this, who breeds Paints, and she didn't seem to know what I was talking about when I mentioned that sabino seems to be linked to roan. Obviously there are tons of sabinos that are NOT roan, but there are also quite a few sabinos that are.
And then I read something in the blue-eye thread about sabino1 and Tennessee Walking Horses, and that breed definitely has a lot of roaned out sabinos. But so do Clydesdales and Shires and they are not supposed to have the sabino1 gene.
So why are some sabinos heavily roaned and some just have 4 white socks, a blaze, and maybe a belly spot?
(Note, when I say "roan" I know that is not the same as a true, dark headed roan. I just don't know what else to call the sabino roans.)
So here are some examples I found on Google to illustrate what I'm talking about. Why do some sabinos seem to be linked with roaning and others do not?

Upon looking for photos to post as examples, I also found a lot of horses that did not fit neatly into either catagory. So what's up with roan and sabino anyway?
