Mostly I'm starting this thread to hear how to colour experts explain Dominant White because it's one of the colours/genes that I am terrible with identifying and understanding (Sabino and LP being the others.. ).
Anyway, please educate me. I've been looking stuff up and can't manage to retain any of it other than creeping around the equine colour site Chiilaa posted says there are 11 different mutations. I can remember that. Haha.
