I know the number of chromosomes wouldn't change. If the genetic material is substantially different on chromosome 20 when comparing the Biewer to the Yorkshire terrier, then that satisfies me that the Biewer is a separate breed developed from the Yorkie & ????.
I wish someone would test the Parti too. It would answer a lot of questions.
Thanks for all the informative discussion!
