Here is the history of the Parti DNA testing as taken from Deb Mullins site:
snowblueyorkies.com
The Tri- color had been showing up in litters from Ashley since 1984 and Nikkos Kennel had been quietly placing them in pet homes and asking people not to say where they got them.
Crownridge and Summit had obtained Parti colored puppies from Nikkos kennels and wanted them AKC registered with their true parti-colors . So in 1999 they convinced Nikkos Kennel to go to AKC and get them registered as yorkshire terriers parti color.
This turned out to be a very lengthy and costly process to Mrs. Lipman,(Nikko's Kennels) as AKC shut down her kennel in 1999 for 18 months to conduct DNA studies of 42 litters sires and dams. She was not allowed to breed or sell or conduct any business during this time.
3 of the dogs tested were owned by Mrs Bogren(Crownridge) and 1 owned by Mrs Gesmundo(Summit Yorkies)
During this study AKC also spoke to several other breeders about tri colored pups born in other bloodlines.
Many highly respected breeders admitted they occasionally had these tri colored pups born.
AKC went back as far as they could with the living dogs. They DNA'd about 42 litters. They also talked to a lot of the "old" breeders and they told them they had always been in the lines but were disposed of.
In June of 2000. The DNA studies of Nikko’s Kennel was completed to the satisfaction of AKC. AKC deciding that after a study of the Yorkshire History and the DNA of the dogs involved in the study they were satisfied that the color can be produced in otherwise normal litters of Yorkshire Terriers.
Hope that helps you..

Hi Diana, I'm glad the AKC is satisfied that the Parti color can be produced in otherwise normal litters of Yorkshire Terriers, because I sure am not. Old records can be falsified, and the Parti color predates the era of DNA testing. And as I said in another post, if the trait did come from another breed and was crossed in to breed standard Yorkshire Terriers for generation after generation, eventually the sign of the evil deed is doing to disappear. In order for my curiosity to be satisfied, I would need to see a DNA breed analysis test done on as many Partis as possible, and I would like to see the MITF (piebald) gene and its upstream regulatory DNA sequenced. I'm a show-me kind of guy.
