Oh dear, I don't want to create more controversy, but I think that Parti-Yorkies got their piebald gene in the same way that Biewers did--by crossing in from another breed. BUT, I have read absolutely nothing about DNA breed testing of Parti Yorkies, so I don't have as much data to go on as I do for Biewers--the evidence is much more clear in Biewers. It would be great to sequence the MITF (piebald) gene in Parti Yorkies too, just to try to get an idea of what is going on. I am willing to keep an open mind. We simply need more data.
