Regarding that parent's head shot in the old thread, would that dog's parents both have had to have a wedge-shaped head, long-muzzle gene to get that head type? And the same thing for the ear types and sets? Would it take both parents passing along those genes to create the head shape and ear types and set?
I'm so sorry to ask so many questions but if I should ever decide at some time to place a deposit on one of the puppies in some future AKC purebred Yorkshire Terrier littler and wait for the whelp, I just want to be sure one or more of them can't come out looking terribly atypical and all that wait be for naught. Even though I'd thought that a recessive gene could show up at any time, I'd still thought breeding Yorkies to one another consistently produced Yorkie-looking puppies and this thread has rattled and worried me. |
Hi, I know that there is a definitive answer for head shape, muzzle length, ear type, and set, but I might have to wait until Monday to find the best answer--I'd like to find a reference that answers all of these questions. In the meantime, here is a link to a National Geographic article which states that about 50 genes determine most of the differences between breeds, and they give a few examples of single gene traits...
