Good points Don. That is just the way it is. I would consider myself at least somewhat black if I had ANY ancestor within the last 200 or so years who was black. It's the same way with the Native American blood I have in me, it was several generations ago, but it's a measurable amount.
Col. I'm reminded of a conversation I had with a dog breeder a few years ago. We had been discussing pure breds and mongrels and she told me something I had forgotten about until I read your post. I have no idea if what she said was true or not . She said that if you were to take a golden retriever ( for example) and mate it with a black lab then take the offspring and mate it with another golden and once again mate the offspring with a golden, that after a period of time all genetic traces of the black lab will be entirely eliminated. She also said the same thing was true in humans and can be demonstrated in only four of five generations.
I had assumed that each succeeding generation would carry a percentage such as 1/2, 1/4 /, 1/8 , 1/16 and so forth unto perpetuity. Does anyone here have any scientific knowledge pertaining to this subject?
