Dr. McDonald Interprets Grandma’s Data

Standard

Most likely fit is 58.1% (+-  0.2%) Europe (all Western Europe) and 19.3% (+-  0.1%) Mideast (all North Africa) and 22.6% (+-  0.3%) America (various subcontinents)

The following are possible population sets and their fractions,
most likely at the top
  French= 0.579 Egyptian= 0.192     Maya= 0.229 or
  French= 0.584 Egyptian= 0.193 Columbia= 0.223
But in fact it looks Latin American … the “Egyptian”
is probably more western North African (at say 10%) with 23 % Maya
and the rest Spain.

“Spot on the Map Plot”: Here the data is plotted as a summary. The green spot represents the average location of all ancestry except Native American and Oceanic. Note that for people with significant sub-Saharan African ancestry this green spot is essentially meaningless. But for people with just European, Mideast, and sometimes South Asian ancestry it is usually quite accurate as far as their average ancestry goes. The geographic map plot shows each continent’s average location, as well as  an overall average (green) excluding the American and Oceanic ancestry.

I asked about why Grandma, a few cousins, and I were getting these strange Eastern European/Russian results:

Eastern Europe in Latin Americans has always been a big problem for Family Finder (which I wrote) as well as my newer versions, which I use here. I know why it does it, but using a single program for everybody makes it near-impossible to fix.  In some people even the new 23andme stuff has the problem. There is a test I do, graph attached, that shows in fact that France (or Spain) is more likely. Other than that, it is very ordinary Latin American.
