I've been called troll so many times I hesitate to start another thread; but I've looked at so many peds now, specifically east german and czech so far, that I probably ought to start keeping like a running tally of what I find. Personally I think Science currently over estimates the significance of nuclear DNA (that which male offspring may inherit from male parent). In terms of reproduction, FAR more is required of/inherited from the female (mitochondrial DNA) parent.
In any event, it's been said that most gsd alive today were sired by a descendant of klodo vom boxberg, and that may indeed be a good rule of thumb? This thread is dedicated to the exceptions of that rule. Again this is just a running tally, work in progress. I'll post them as I find them. Genetically speaking, if your male dog's sire's sire's sire's sire traces all the way back to one of the dogs in this thread, his nuclear DNA may be somewhat "diverse."
