I'm not trying to be argumentative, I'm just trying to get people to really think about this, so here we go .... :-)
The point that I was trying to make is: that God did not create a male and female Yorkshire terrier. History shows that the breed began by breeding other terrier type dogs together.
The white gene (parti gene in this case) is a recessive gene and will only display itself if bred to another white gene carrier. So even if history shows that the foundation dogs NEVER, EVER, bred to any color but grizzle, black/tan, black/gold, blue/gold, blue/tan, that doesn't mean that none of those "standard" colored dogs, didn't carry the recessive white gene.
I'm sure there are other lines of Parti gene carrying, Traditional colored yorkies out there but until there's a DNA test to uncover the gene or until the carrier breeds to another carrier, the Parti color will remain hidden for many generations.
Example: Say that a litter of 4 pups were born, one was parti colored. The Parti pup was given away and kept a secret; the other 3 traditional pups were sold with AKC papers. Are the 3 traditional colored AKC registered pups more "Pure" (bloodline wise) than the Parti colored pup? Both mom and dad were parti carriers and if bred together again, would produce more parti and traditional colored puppies.
These two carriers continue breeding, not to each other but to other Yorkies. They will still pass that parti gene onto 25% of their offspring - those pups just looking like a traditional colored dog. They produce a total of ... 50 pups over the years. 12-13 of those pups will be carriers. Those 12-13 carriers produce 600 pups during their lifetime - 150 of those pups are now carriers and it goes on and on. Just something to ponder, I don't think anyone can guarantee that their "Pure" yorkie doesn't carry this recessive gene, unless your dog has produced a Parti colored pup at some point in it's lifetime - in which case, it would have been bred to another Parti gene carrier to produce a Parti colored pup.
Now that Parti colored Yorkshire Terriers are allowed to be registered with AKC, in order to keep honest people honest, it may be a good idea to have several generations of any newly uncovered Parti lines, to be DNA tested. This would insure that there was no deliberate or recent "behind the kennel breeding?"
