Genetics are way more complicated than you think. The Mars test may have shown your dog as pure yorkie although it is parti colour. Not sure how that works when the yorkie does not carry the pie bald gene to produce that pattern. Interesting isn't it?
So if the mix is dilute enough would Mars show a purebred? Dilute meaning the mix occured many generations ago but that gene to create the colour pattern is still carried forward.
I still have no idea why anyone would purposely set out to wreck a breed that is so not the breed standard.
There are wrong colours in other breeds that will not ever be recognized by the parent club. Black and white German Shorhairs pointers for example are a fault and are not recognized nor bred for. They are sold for pet if one turns up.
Why the yorkie ended up being targeted to try to destroy the breed is beyond my understanding.

So you don't consider the yorkie flashy enough to be in the BIS?

The Mars testing was dicussed here last year... http://www.yorkietalk.com/forums/bre...-accuracy.html

In Mars' own words...."While Wisdom Panel Insights is not designed as a pure bred test our results indicate that St. Nicholas' recent ancestry only includes Yorkshire Terrier".

So you have AKC's DNA profile proving parentage only and the Mars test (with the above highlighted qualifiers). Do you really feel that is enough to sway the parent club? Unless a test comes along establishing breed purity, I don't think there's enough there to convince the parent club to allow Partis in.

"The genetic makeup for the Yorkshire Terrier is:

asasBBCCDDEEGGmmSStt

S Self colour to totally pigmented surface si Irish spotting involving a few definite areas of white sp Piebald spotting sw Extreme-white piebald

Most breeds without white markings are SS but from time to time markings do appear and in general appear on toes, chest or muzzle. These marks can be present at birth and are lost during infancy. The ones that persist are not other s alleles but to minus modifiers at the S allele and will be limited to those minute amounts in those locations.

Irish spotting is also limited to certain areas of the body as the dominant S is, ruling out either gene in the makeup of Parti Yorkie Tri Colors or Biewers. Limited to forehead, chest, belly, feet and tail tip.

Piebald shows much larger amounts of white on the dogs then the Irish spotting gene.

Extreme-white piebald is seen in those breeds which are white in color. As a result of this double carrier of swsw all other colors can be suppressed. (From Malcolm Willis "Genetics of the Dog")

Destroy the breed? Have you looked at all the Puppymills with yorkies. They are the ones destroying the Yorkie.
The Partis are not trying to destroy the breed they just want a separate color variation.
I am carefully choosing what I am breeding, I am not breeding trash out to destroy the yorkie.

Very well Said Lorraine!

I don't think Carolyn is doing seminars.

Absolutely!

Merles dont pertain to yorkies so that point is mute. The merling gene is whole different thing.

Because the YTCA will not even discuss with the parti people a way to try make both sides happy nothing will ever get resolved. More and more carriers will just start showing in the ring, its inevitable and over time most of your yorkies will carry the parti gene, if they dont already. The only way to keep them separated is to give them their own standard and class.
So why not talk with us and try to get it sorted out so we can have our own variety and you can keep your standard as is.
No one ever gets anywhere if they wont even talk about it.

It's exactly the same.

Well I can say this with Absolute conviction. None of my Yorkies have this Parti Gene and they never will. So for you to make that type of statement is basically a bunch of Hogwash. Oh and The breeders I associate with also do not have the Parti gene in their lines either.

Of course I dont know what lines your dogs have but I do know some of the big names do have it in their lines.
There were parti pups born from the sire Ch Hylan Acres Ridin the Storm and a daughter of Ch. Durrers Mighty Obsession.
Durrers Ace High goes back to Finstal Icing and Finstal goes back to Streamglen Shaun, the same line some of the partis come from. HMMM

Guess it's good that none of those dogs are in my dogs peds then huh.

I think what shes saying is their will be more parti carrier in the ring in the future and more parti carriers bred to yortkies in the future so the gene pool will be diluted in the future
