No, that is not true in all cases. "The Z gene also works on bay horses. It dilutes the black mane and tail to white and the black legs to flat brown with dapples, but it leaves the red body color alone, because it only affects black. These horses are A-E-Z-."
So how do they determine that it is a silver dapple bay, not a chestnut? Where did you learn this? It is interesting.
