I know that Mr. Biewer had other breed dogs. Could DNA determine which breed supplied pie-bald gene? |
I've heard different stories as to which other breeds Mr. Biewer had at the time--I'm still waiting for the definitive answer to that question, because that could be the answer to where the piebald gene came from. But yes, DNA analysis could determine which breed supplied the piebald gene.

There are really good & ethical breeders out there. There are also the GREEDERS, however, who breed everything under the sun. I can see very easily how other breeds could be mixed in - even on purpose - to obtain a desired look.
Thanks again. Keep the information coming!

Here is another smoking gun. I was going to propose that someone cross a Biewer to a piebald Maltese to see whether the offspring would be piebald. If the offspring were piebald, that would prove that Biewers definitely carry the piebald gene. (This kind of cross is what geneticists call an allele test.) But I didn't say anything because I thought it would be unethical to ask someone to do that kind of cross. But guess what? While I was googling Biewer and Maltese, I found this ad:
MORKIE German Biewer Yorkie / Maltese cross | North Port | eBay Classifieds (Kijiji) | 27676387. Someone has already done the cross, and the result is a piebald dog! Boo-yaaaa!!!!! I will attach a photo of the dog in case the ad disappears.
