With research telling us the "foundation dogs" that have produced tri colored puppies, whether biewer or partis, originated from kennels in the UK...I would say any mixed breeding, if it occurred, took place there. |
My source regarding the biewers comes from the biewer breeders. Are you familiar with Leon Whitney's book "How to Breed Dogs"? It's an old book, I'm sure now out of print. But it explains the mode of inheritance of color and pattern for most all breeds. I'm not going to spend my holiday weekend researching but it would be interesting to know if the piebald pattern is a simple recessive gene.
