I'm gonna say he carries tobiano/splash/frame and definitely sabino. Be worth testing. Sabino and frame will keep the white off the eyes and add to jagged markings(IE: no blue eyes) but splash will call for high leg whites and belly and the white under the jaw. He may not even carry frame, but only sabino/splash -- definitely test though. It's worth the money and fun!
Tovero for sure! But APHA will classify as a tobiano because of their self-outlined rules unless you can provide genetic testing that states otherwise :)
