White markings are tuff to truely pin point.
Some say its a pinto trait to which I ask then how do Arabians get white markings? A pure bred Arabian does not carry the pinto gene (yes the exact gene has been found in pinto horses but not the Arab) and Sabino/Rabicino in Arabians is not produced by the pinto gene. Unlike other breeds the Arabian is blood tested before registration is allowed to ensure pure status. So saying "color" was introduced is not possible.
Arabian foals do not get lethal white syndrome because they do not carry the pinto/sabino gene that other breeds do.
I think there are more factors at play than what us humans will admit. The whole control freak thing humans have going on,lol.
Arabians don't have FRAME which causes lethal white, no. They DO have sabino, which does NOT have anything to do with lethal white. Arabians also have rabicano, another of the pinto genes, and probably have splash white too. They also have dominant white, yet another pinto gene. In reality, the only pinto genes they DON'T have is tobiano and frame.
I would definitely say this horse is displaying sabino. The leg markings are irregular, showing distinct arrow-head markings. Sabino doesn't cause irregular face white - it likes faces to be symmetrical and neat, narrow white on the center of the face, just like this horse.
So which "exact pinto gene" are you talking about? So far, a lot of them have been identified - sabino 1, tobiano, frame, splash 1, splash 2, splash 3, 5 varieties of dominant white. Still to be isolated is rabicano, an unknown number of sabino genes, at least one more type of splash, and at least 6 more dominant white. Which one are you talking about??
