What to do at the GEDmatch site

Dec4

A DNA cousin who just uploaded his ftDNA results to GEDmatch asked me what he could do with them, so I decided to write a blog post to answer this question. Here are my favorite things to do there:

  • make pretty pictures of your populations ancestry – called the Ad-Mix page
     (see more on that below)
  • get a list of possible relatives who have tested with other companies as well as the one you tested with, that is the “One to Many” option on your home page. Email addresses are shown but you cannot just click on them, you can cut and paste the first part but then you have to retype the ISP  (prevents spam)
  • look at a specific area of one chromosome to see who else matches you there – “Find people who match
    with you on a specified segment”
  • compare your GEDcom to one other to see of you can find that elusive MRCA
  • compare your GEDcom to all your DNA matches that have uploaded GEDCOM files

Phasing: or how to look at what you inherited from one parent only

So in the images in my last post about GEDmatch you may have noticed that my Dad has less Mediterranean, Siberian, and Southwest Asian than I did. Perhaps you are wondering if there is a way to see what I got from my mother? Separating what you got from which parent is called phasing and you need to have at least one parent tested and uploaded to use this function at GEDmatch. The Genetic Genealogist has a good explanation of phasing in this blog post – http://www.thegeneticgenealogist.com/2012/06/07/gedmatch-com-adds-phasing-tool/

Here is what I got from my mother although GEDmatch cautions that the phased data may not be all that accurate.

 

 

Eurogenes 12b does not have as many Northern breakouts but does include Finnish which is of interest since Dad has several Finnish matches so I collected all the Finnish percentages. As you can see Mom had some too and Shipley got more than I did:

GEDmatch: a wonderful tool

Nov5

One of the best tools around for genetic genealogy is the GEDmatch site which allows you to upload your raw data from whatever service you used and compare it to everyone’s data at GEDmatch in many different ways. But my favorite tool is the pretty pictures of your ancestry mixtures (called admixtures). Here is mine using the Eurogenes K12 calculator which seems best for us Northern/Scandinavian folk:

 



What does it all mean? A discussion of these populations is here at the Eurogenes blog.
