Every dog breed is defined by all criteria mentioned in the standard. In the paragraph other colors we have the sentence: "The breed is defined by its colour, ..." This sentence is a quotation not from the standard but from an exaggeratedly formulated personal opinion. If the breed were defined only by the coat colour, a German Shepherd would also fit well into this definition (apart from the melanistic mask, which Yorkies should not have). I'd suggest, we rephrase that. For example: The standard prescribes clearly defined fur-colors, and non-standard colors may ...
A Black and Tan Golddust Carrier and a homozygous Golddust Yorkie both with short shorn fur
The allele on the B-Locus determines whether a dog produces chocolate brown or black eumelanin. If the dog has the allele B (BB or Bb) he produces black eumelanin. Only if the dog has the recessive allele b homozygous (bb) he produces chocolate brown eumelanin. For example the rough-haired dachshund can be black and tan or choco and tan . The coat colour gene B or b doesn't have any influence on the health. They are all healthy dogs. Why should anyone doubt the health of a Yorkie in choco and tan? Yorkie breeders without knowledge about dog coat colour genetics sometimes assume it was a mutation, but it isn't. It is the unexpected appearance of a homozygous dog, genotype bb, born from two genetic carriers, from two parents with genotype Bb, phenotype black and tan or blue and tan, which fully correspond to the breed standard. This has nothing to do with mutation or crossbreeding with other breeds. It just occurs very rarely, because the carriers of the allele b are very rare in this breed and there is an extremely low probability that one carrier will be mated with another. So don't be worried if one or two puppies in a litter of five has a non-standard colour. If you are in the american yorkshire terrier club or in the VDH the individual will be excluded from breeding. If you're in a different umbrella organization, it won't. The same applies for the allele e for recessive red on the extension locus and the piebald-gene sP.

It was also known that ernest hemingway's grandfather had a white yorkshire terrier named Tassel. Trekarraz (talk) 16:31, 13 March 2023 (UTC)Reply[reply]
It's a pity that my content was deleted in the Article, I actually wanted to show that there were other colors of the yorkshire in the past and is not just a new phenomenon. I myself have yorkshire terriers and am very interested in their history. Also the link of the oil picture is very valuable in the article. It shows an almost white yorkshire terrier from 1885.

Yorkshire can weight more than 3.2kg. French language page put a max weight at 5kg. My own yorkshire is 4.1kg and clearly not overweight.
