Please see figures 107 & 108. If dogs of >this type are a part of the GSD gene pool might that not be where >the pandas come from? I'm surely no expert, but this is my take on the above. Merles were an early part of the GSD breed, as were brindles. However, IMO, the M gene was bred out a long time ago. Merle (M) is an incompletely dominant trait. As such, it would not tend to be "carried" along, silently and unseen, throughout the many, many years and generations only to pop up unexpectedly as the "panda" color trait apparently did. And while "cryptic" (phantom) merles do appear in the breeds where the M gene is common, one would expect that, if such animals existed in any significant number within the GSD gene pool at large, that at least one of them would produced a Merle GSD puppy at some point in time, and probably a lot sooner than was seen with the pandas. <shrugs> At any rate, the color was studied and you'd think that they would have eliminated M as a possibility right away, seeing as they DO have a genetic test for Merle now. -- Karen C.
