I’ll apologize in advance for rehashing an old thread. However, I found the X-Factor Breeding Theory tread to be very interesting and worthy of study. The potential impacts on a given breeding program could be profound. If there is a quantitative method of reinforcing a potential breeding output, I am all in….

So, I found what I think was a very good example:

I objectively back check this against the 4 generation peds on a few of the dogs that I have, and I thought it was fairly accurate.

IMHO, the “Black Holes” mentioned in the article can NOT “have little or NO effect on the offspring.” Rather I think that these preserved voids house the respective recessive traits of the sire and/or dam. I think that these holes are the traits that “skip” a generation (based on the logic) and are more obscure. I can’t manage to get my head around the idea of something being there and then it’s just not? That defies logic and some basic genetic principles and physics, IMO.
