Po- Oh yeah, more genes to muddle my brain. Lol. Are things such as splash, frame, and sabino common in all breeds? I've mainly heard them used in Paint, QH, Arabian, and such. I wasn't sure if they were common in the Appy world unless it was an appy crossed with a pinto/paint.
Look up the term "leucistic" for some bizarre pure "white" animals -- also related to 'pie-baldism'. Some leucistic dear resemble sabino patterns seen in horses, it's quite interesting.
The same pattern anomaly can be seen with snakes and other reptiles too.

I'm NOT saying all the genes are the same but just suggesting that what ever causes these phenomena could be related is some very minuscule way
