Unfortunately, they have been accepted into AKC registration but that was based on the registration numbers of sire and dam and who knows where the mix happened? At that time, DNA was not able to be tested as it was today.
The Biewers also a parti colour Yorkie that come from Germany but not recognized by the FCI or the German Kennel CLub, have proven they were the result of a mix and have very little yorkie genes. It is on their website when they chose to have that information on there.

OP the answer is a very beautiful purebred Yorkie with a coloration the YTCA considers a fault and will not accept so they cannot be shown in the ring.

Hmmm uh wow, though they were officially accepted in 2000 when the DNA testing was established as credible enough to be accepted by the federal courts of America; thus the AKC would accept the canine DNA proof showing the Yorkies that were carriers of the recessive parti gene, were full Yorkies and furthermore full Partis (even non-line bred) could be established as full Yorkies...and well all those who were breeding crosses as Partis and submitted their dogs DNA we really called out on the carpet over it...strange historically speaking there's a lot of "unpopular" proof to their existence...where did the "cousin" Biewers come from then?-an American Parti line. Partis unlike Biewers are not inbred continually.

Anyone actually know and want to post links and official AKC documentation for this?
