So now we have the question - can a form of sabino cause blue eyes, or do we have to admit and realize that our Arabians are actually carrying sabino AND splashed white? And why did it take so long for either to manifest physically on a regular basis?
The reason they took so long to manifest themselves, is because of the Arabian breeders. Those things were purposely avoided and bred out of Arabians in the U.S. And Canada for a very long time.
The big name breeders, trainers, and judges didn't want those markings, so they were considered conformation faults and bred out. Plus, they started the myth that well bred Arabians just simply didn't have those markings.
As I said, Khemosabi paved the way for making those markings acceptable. He was such a stunning example of the Arabian breed, that people forgot those markings were considered unacceptable.
Khemo was also extremely prepotent, and stamped his look and temperament on not only his get, but his grandget. I loved that horse. I even got to meet him once. He truly was a king, and knew it.
