In Response To: Re: Haplogroup I (M170) ()
I'm gonna quote one of the scientists in the documentary "Motherland: A Genetic Journey" or perhaps misquote her: "Those two tests results are just a snippet of your ancestry."
I know you know this intellectually, but I am going to pound it in one more time. Think of a funnel. You are the spout of the funnel. The DNA testing that you have done (Y-chromosome and mtDNA tests) reflect ONLY the outer 2 edges of that funnel. You have no test results for all those other people, ALL of whom could have been African.
So, Art, go get the "other" DNA test done. The one that gives you percentages from ALL of your ancestry. That is where your "African-ness" will show up.
I am the opposite example from you. I have tested four lines: maternal and paternal grandmothers; maternal and paternal grandfathers. All four of these lines connect back to current-day populations in Africa. But someone asked me: "Then where do you get your color from?" (I have medium/light-brown skin). Yes, I have tested for all four grandparents, BUT that still means I have tested only 4 of 8 great-grandparents; 4 of 16 great-greats, and so on with the tested percentage halving with each generation I go back in time. 100% of grand parents, 50% of greats, 25% of great-greats, etc. That's a lot of un-acknowledged dna floating in my body.
I have also had the 3rd type of test done and my results are 82% Subsaharan African and 18% European. My skin color is obviously from those other lines that I have NOT yet tested, and at this point don't have anyone TO test. For example: My paternal grandmother's FATHER was said to "look white." But I would need my grandmother's brother or his male descendant to test that. We have no information on her family so cannot test that story. And based on appearance, my mother's family likely had some European ancestry back somewhere, though probably not as recent as my father's family.
