Hey, Roberta, thanks for the great insight !

Because 100% of your DNA divided by 64 GGGG-grandparents equals 1.56% of each of those GGGG-grandparents. DNA sequencing is essentially another term for reading the DNA double helix or determining the sequence of its nucleotides or bases. Ive also had more people argue with me that their ethnicity breakdown is gospel. Expectations of what it means for a population to be racially and ethnically diverse may differ.

Especially that my Greek/Italian percentage is so high! 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. In this America Counts story on racial and ethnic diversity, we cross-tabulate the race and Hispanic origin statistics, as data users often do, such as with the 2020 Census redistricting tables. Then I transferred my Ancestry DNA over to FTDNA, and their estimate is 30% Scandinavian, 28% British Isles, 26% West and Central Europe, 11% Southeast Europe, and 5% East Europe. Genographic Project results are the least like the others, and the most difficult to quantify relative to expected amounts of genealogy. Youre much more than a pie chart and a handful of percentages.

Remember when you got your AncestryDNA test results? Cultural ethnicity differs from genetic ethnicity. The Genographic Project results do not fit well with the others in terms of categorization.
