Comparing my DNA Ethnicity Chromosome Paintings at FTDNA, 23&me, and AncestryDNA

 

Ancestry Composition Chromosome Painting at 23andMe for my DNA Test




FamilyTreeDNA's Chromosome Painter for my test
Which was an Upload of my AncestryDNA taken in 2014




Chromosome Painted Ethnicity of my AncestryDNA test


Summary:  There isn't much which stands out in my DNA painting but I can see a few things.  Ancestry and 23andMe seem to agree that I have DNA most resembling folks from Finland at the tips of Chromosome 1 & 2.  Those are the Paternal Tips for both 1 & 2. My Mom has no Finland ethnicity showing at her Ancestry test so that did help me to assign the parent portions. FTDNA and 23andMe also seem to agree on a small snippet of African DNA on Chromosome 6 and since it's not showing up that way on Mom's test there it should be paternal.  

By consulting my DNA Match Painted Chromosomes at DNAPainter I can see that the Chrom 1 & 2 segments are from my paternal grandfather's King / Manire ancestry so that connection would be somewhere back along those.  The paternal Chrom 6 for me is almost all from my paternal grandmother and this looks to be in a section which would be either Morrow / Sutton or Frizzell / Manley.  I believe this is the same portion that FTDNA at one time was identifying as Sephardic Jewish Ethnicity.

I looked at my Mom's Ancestry DNA Chromosome Painted Ethnicity.  Hers is a lot more colorful than mine.  Where she has Norway, Denmark & Sweden, and Wales Ethnicity the ethnicity pretty much covers the entire chromosome side.  I've not been able to figure out which side of hers is which parent yet.  I hope that I can eventually.

Using DNApainter to visualize match "coverage" & collect more clues

I've been using  DNApainter(a WONDERFUL DNA analysis tool by Jonny Perl) for a while now.  I'm not sure the exact date, but it couldn't have been more than a few minutes after I read about it in the Genetic Genealogy Tips & Techniques Facebook Group.  You can learn more about both of those by clicking on the linked text.  DNApainter is free but has additional tools available for subscribers.  Today I subscribed and I've been playing around with it.  I wanted to see what kind of coverage I had from my matches at GEDmatch.  I had used my kit and my Mom's kit to phase my DNA matches.  My Dad passed before we began DNA testing.  While the Paternal Phased kit is not a true comparison against his it will show all the matches I have which aren't Mom's which are presumably paternal. 


  • At DNApainter,  I created A New/ Blank Profile --I named mine Marie GEDmatch
  • At GEDmatch, I ran Tier 1 Matching Segment reports for each phased kit and saved each as csv files. You should set the minimum cMs high enough to reduce by chance matches.  I set mine at 12 cM for this.  I can delete matches if necessary later.
  • At DNApainter, I opened the New / Blank Profile and used DNApainter's premium feature to Import Paternal phased (P1) & Maternal Phased(M1) match list.
  • As I imported each phased group, I chose a color, name, and identified it as paternal  or maternal matches.
It was abt at 74% coverage(I wish I had taken a screenshot then but I didn't) and I wanted to import the data from the painting I had done on my main profile.  I exported the segment information from that main profile and imported it into the Marie GEDmatch profile.so that I could identify more matching segments.  

Below is a screenshot showing only the GEDmatch Import as Active(using the key)



Once the main profile is imported here is how mine looked. Now to look at each chromosome and collect the clues.
