I don't know if the foreface is a from a single gene...it may be. The only point I'm trying to make is that not all recessive traits follow suit like the pie-bald gene, which we're all more familiar with (as in 2 partis bred together will only produce partis).
Like in the case of coat texture. All the characteristics of an ideal Yorkie coat are from recessive genes. But it wouldn't be true at all to say that you will get 100% silky coats so long as you bred 2 dogs with a silky coat together. |
So true, not all traits are the result of a single gene, but according to the website linked a short muzzle could be traced to a single gene, although, I don't know if that website is accurate. The yorkies hair, as you say, comes from a complex mixture, and from my understanding, mixtures are even more common than 100% silly, but my point is if you want to know what the offspring will look like as an adult, look at the parents, this is a great indication! I think some people think that the offspring will somehow be so much cuter than the parents, and this is usually not the case, unless the breeder really knows what he/she's doing.
