be sure to watch until the end for full 2013-11-11 · Each generation back your number of ancestors double, until you are descended from so many people (e.g. 20 generation back you potentially have 1 million ancestor) that it is quite likely that some people back then are your ancestors multiple times over. If we double the number of ancestors in each generation, 2 parents, 4 grandparents, and so on, we can see that by the time we are back 10 generations, we have the potential for 1024 ancestors. If we were to go back to the time of Charlemagne, we would find we had the potential for 281 trillion ancestors all living at that one moment in history.

(For example children have 1/2 DNA of parents and 1/4 DNA of Grandparents, After 10 Generation 1/1024 DNA and after 100 Generations 1/2 100 DNA). Is there a point (value of n) when descendant is no more related to ancestor and is similarly related to random individual from an ancestral population. Personal DNA testing as well as DNA studies are revealing that quite a few white Americans as well as white Latin Americans have some minor African DNA and are not 100% genetically European. In many cases these small African %’s might be traced back to one single distant African ancestor from many generations ago i imagine. In my case it was 1.3%, which equates to a 100% African ancestor 6 generations ago, circa 1800. In your case, it is roughly double my contribution, meaning if the African heritage was introduced by a 100% African it would have been only 5 generations ago, approx 1830. As of 2013, estimates for the age Y-MRCA are subject to substantial uncertainty, with a wide range of times from 180,000 to 580,000 years ago (with an estimated age of between 120,000 and 156,000 years ago, roughly consistent with the estimate for mt-MRCA.).
