Admixture : Eurogenes - Travis

I took advantage of the free tools at Gedmatch.com to compute the admixture of my DNA using the Eurogenes K13 project.  Admixture is when two or more previously separated populations interbreed.  The Eurogenes project is for those with primarily European ancestry, and more detail can be found at the Eurogenes Genetic Ancestry Project blog.

Population  

North_Atlantic 44.47%

Baltic                 26.11%

West_Med           12.66%

West_Asian          6.16%

East_Med              5.55%

Red_Sea               0.15%

South_Asian          1.98%

East_Asian -    

Siberian -    

Amerindian           1.29%

Oceanian -    

Northeast_African  1.52%

Sub-Saharan          0.10%

This paints an interesting picture of my deep ancestry with only slight variation from 23andMe, showing traces of Native American.

Tracking my atDNA matches

I've been spending a lot of time lately maintaining a spreadsheet of my autosomal DNA matches as suggested by Jim Bartlett and detailed at Kitty Cooper's blog.  In the meantime I've been reading and trying to learn as much as I can about how autosomal DNA works.

I've added the matching detail and the chromosone mapping from the first set of 23andMe matches as well as those from Gedmatch.  I have over 1000 matches at 23andMe alone - it will take me some time to get this all down.

I'm lucky that both of my parents have tested now at 23andme. Mom's results are ready, dad's are just about ready.  Because they've been tested, I can easily tell which of my matches come from which side of the family. 

Using the spreadsheet, I will triangulate among the matches to identify relatives that match me at the same chromosone segments.  This should help identify that we are descended from a common ancestor.  Then, hopefully, we can use the family tree information to determine which ancestor.

Right now, I've clearly identified the common ancestors of two matches on my paternal side and one match on the maternal.  There is so much more to discover!

DNA : Eileen's Ancestry Composition

Eileen's results processed from the DNA test she took at 23andMe and her results were not quite what she expected.

Here is the "Conservative" estimate of her genetic make-up : 97.9% European, 2.1% unassigned.

There was no trace of any Native American, or any other ancestry for that matter, than European found.  A full 51.1% of non-specific northern European and 43.6% of non-specific European.

Here is the "Standard" estimate of her genetic make-up : 99.6% European, .4% unassigned.

This is a better break-down, showing 18.7% British & Irish, only 58.3% non-specific northern European and 21.7% non-specific European.  The .8% eastern European is interesting, as this is an unknown aspect of her family history.

Here is the "Speculative" estimate of her genetic make-up : 43.2% British & Irish, 9.8% French & German, .7% Scandinavian and 38.8% non-specific northern European.

The 2.4% non-specific southern European and 1.2% eastern European will be the most interesting to see if we can discover during this DNA research.  There is no known history of this ethnicity in her family.

Eileen was surprised that no Native American showed up on the test, and I was surprised that we weren't related to each other.  We have Swiss Mennonite families in the same area, I thought for sure we would be distantly related.

The good news is that we are hopeful that her mom and brother will test with 23andMe as well.
