Yes, to a point. A small white spot on the chest is standard for a trad. yorkie. On odd places (toes, mouth, etc.) more than likely, yes. To be sure, I would try breeding the yorkie with another parti and see what happens. The gene is stronger in a Biewer since it is all that is in the line. It is bred specifically for that trait so recessive gene becomes the dominant. (if that makes sense) So you may want to find a Biewer to breed it with to "pul out" or "enhance" any possible traces of the gene.

No not at all! The Partis, maybe. You cant tell with the Partis because you dont have such a background in most cases that would go back far enough to rule it out. In the case of a Biewer though, it is one line that has been bred to enhance that specific trait and has dominated the once recessive gene. It is like saying a dog born with 3 legs would produce 3-legged dogs. It does NOT mean that it is a mix breed. That is two totally different things. Gene mutations and mixed breeds. The gene mutation is something that naturally occured not something that was mixed up.
Hope that clarifies
