My father's Dodecad results - 1. Pie charts

The Dodecad tool was the first tool I used at GEDmatch to parse out my DNA, and I was somewhat shocked when it knew immediately that I was from Utah.  (Technically I have lived elsewhere, but really Utah is the locus of many family generations....)  This is where I first heard the term "CEU".

 Dieneke's anthropology blog is a formidable read for someone who has no background in anthropology, but still covers many interesting threads.  There are four tools through GEDmatch from Dienekes that section up the world in different ways and provide interesting perspectives, which we are then left to interpret and analyze.

I am going to show the pie charts for the four tools together, so I can compare them against each other.

This is Dodecad V3 -- this is the first calculator I used and the one that immediately showed Utah (CEU) as the top result in the population finder.



















This is Dodecad K12b.  I like it, because it uses 12 populations and so gives more choices to compare. 





















This is Dodecad K7b for my dad -- the world is grouped into only 7 types, and so results vary.  However, it should be mentioned that each test still has sample populations that test out with an average percentage for each type.  So, for example, there are British participants in each test with known, full British ancestry.  They will test differently with different amounts of each component in each test.  So, in other words, it's likely that your main group that you align with should still be available for comparison to see how much you coincide with or trend away from the average.


Below is World9 -- World9 is unique compared to the others, in that it actually creates an Amerindian component.  This shows a little higher than what I have estimated were possible if my g+ grandfather Solomon Mack were actually 100% Native American in a previous post, which we know he isn't.  So, it's either a Finnish thing, or a Finnish and hint of Native American that can account for this result.

One thing I might want to try later is narrowing down which chromosomes for my dad show high in Amerindian with World9 and see how that compares with other tools -- like the East Asian & Siberian above, his McDonald painting, my painting, etc.  I have already found a Finnish person linked to the largest "Siberian" segment, but haven't ruled out a small segment on the 17th chromosome as Native American.
