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?"

The thing I find the most interesting in the parti colour is that they don't seem to be showing up in litters of those show breeders that have immersed themselves in Yorkies both in breeding and the show rings. If they were, you would bet we would know about it.
I am talking about breeders who know their pedigrees, the kennels and dogs in those pedigrees so far back to about the time they started in the breed. That's a lot of years of information. I am talking about show breeders that have been around 20, 30, 40 years and would have a fair number of litters and puppies under their belt. I am talking about the show breeders striving to breed to the breed standard and live and breathe Yorkies. The ones who don't breed only to fill the pet market for whatever bucks they can get.
Why would we know about it? Show breeders also have to go out on their lines, use someone else's stud for breeding and/or buy a Yorkie from another show breeder. If something was showing up in the whelping box, you would bet word would get around.
In the 10years i have been participating in the show world I have yet to hear of fellow show breeders producing a parti colour.
That's what makes me very suspicious of the origins of the particolour.
I do not believe the maltese or maltese alone were used in creating the particolour or Biewer, don't really care what you want to call them. I believe the maltese may have played a role in it, or not but I do believe the Shih Tzu was in there somewhere.
