Heres a closer look at how Ancestry scientists approach the topic of ethnicity regions. If you like to learn more about ethnicity estimates and how they are calculated, you might want to read this article, Ethnicity Testing, A Conundrum. Ethnicity estimatesare generally accurate to the continent level, although not always at low levels. Because we cant tell exactly how much of any ancestors DNA we actually do receive, we have to use the average number, knowing full well we could have more than our 1.56% allocation of that particular ancestors DNA, or none that is discernable at current testing thresholds.

Human beings share about 99.9% of our genetic code: the parts of our DNA that program us to have the same organs, the same type of metabolism, and other basic functions. These improvements reveal that the U.S. population is much more multiracial and diverse than what we measured in the past. My question is whether the 3%, or so, has some genealogical significance or is merely the remnant of historical inheritance due to something like Roman era AJ intermixing?

Absence of evidence is not evidence of absence, except in very recent generations like 2 (grandparents at 25%), maybe 3 generations (great-grandparents at 12.5%). The Genographic Project results do not fit well with the others in terms of categorization. The chart above shows how much of a particular generation of ancestors' DNA you would inherit if each generation between you and that ancestor inherited exactly 50% of that ancestor's DNA from their parent. The presence of the Hispanic or Latino population as the second-most prevalent group spanned the entire continental United States, with large numbers of counties in every region.
