I have to follow up on a topic with faults and genetics....
I'll start off by saying I do not know everything about genetics but it was said that the color or off color in the yorkies is not caused by genetics well I have to disagree because just like a bad ear set, under bite, overshot bite, wrong coat texture, bad topline, low tail set ect....all plays into genetics. The reason we breed to standard is just that...genetics play a BIG part in breeding.
Knowing a dog has a bad rear, bad fronts or a bad topline you don't breed that animal because you'll pick up those "GENES" and that is "genetics". Just as in color it's in the "GENES"! So, being called wrong in that color is not genetic. The yorkie has to be a "CARRIER" which in terms means "GENETICS".
So when breeding and you get all those faults it's in the "GENES" of the dog your breeding so therefore it's "GENETIC".
Had to clear that up
