It may of course be rabicano, but since the mare also got a lot of sabino traits (belly spots etc) I'm leaning towards sabino. It could be a combination of both of them as well
Well, very little is known about rabicano, and the only sabino form known is SB1. There's a whole lot of sabinolooking patterns where nothing is known as far as genetics goes. I'm sure they could combine and express at the same time in all kinds of ways
Depends on just how recent it is Last time I read into the subject of Brown (At) was about a year ago. If it's some new report or paper added after that, then I don't think that I've seen it.
