Pinehaven, your first source is a breeder who sells these dogs, and second and third study didn't include any Yorkshire Terriers, which is important if you are using these as sources because there can be huge differences between breeds. |
There are many "responsible" breeders who breed "off colored" yorkies into their show lines to improve/enhance their show prospects coat color and texture. According to the YTCA's standards it states that the only acceptable color is steel grey and tan. That would mean (my thoughts here) that anyone who is using a black and tan or black and gold in their breeding program is breeding in "undesirable traits" unless the yorkie they're breeding to is known to be homozygous for the grey dilution gene (since half the litter would grow up with black coats because they will not have the grey gene). Please don't get me wrong, I own and like black and tan yorkies :-)
Basic color genetics in the dog are fairly simple but it can get pretty complex depending on the breed. In the Yorkies we are talking about simple genes at work and not multiple dilution genes, coat patterns or gene modifiers that are affecting the colors.

If your goal is to show the offspring, probably not - you may make some nice looking traditional colored gold carriers and if your female also carries the gold gene maybe a few nice golden pups.
Personally I don't care what color the dog is, if he is not the quality that I'm looking for, I wouldn't recommend breeding him to anyone.
