Genetic Affairs Instructions and Resources

I’ve created this summary article that includes links to the various step-by-step instructional articles I’ve published about Genetic Affairs, a wonderful DNA analysis tool. I’ll add more articles as they are published.

Genetic Affairs is a third-party tool created by Evert-Jan Blom that works through the Genetic Affairs website for FamilyTreeDNA and 23andMe and is integrated into products for other vendors such as MyHeritage and GEDmatch. Unfortunately, one vendor, Ancestry, has issued a cease-and-desist order, preventing the usage of Genetic Affairs and other third-party tools altogether for customers who have tested there.

Different features are available at different vendors based on their product offerings, as noted below.

AutoCluster

This article explains the basics of AutoClustering of matches and how autoclusters benefit genealogy.

AutoTree and AutoPedigree

This wonderful tool scans your matches and their trees, and constructs trees of you and your matches that share common ancestors. The best thing about this tool is that it reconstructs trees of your matches to each other in a cluster, even if you DON’T share a common ancestor in a tree with your matches (that also match each other.) This tool is HUGELY helpful in identifying ancestors that are unknown to you and includes the option for Y and mtDNA to be incorporated into the trees if you’ve taken those tests at Family Tree DNA.

AutoPedigree + WATO

Article: Genetic Affairs: AutoPedigree Combined AutoTree with WATO to Identify Your Potential Tree Locations

WATO, short for “what are the odds,” is a calculation method that provides ranked hypothesis that show you where you “might” fit in the composite tree of your matches. This is the “AutoPedigree generate hypothesis automatically” option under AutoCluster analysis and is particularly useful for people with unknown parentage, unknown close relatives or clusters that they can’t identify.

  • AutoPedigree+WATO can only be used with results at FamilyTreeDNA, and not at any of the other vendors for the same reasons as AutoTree/AutoPedigree. I encourage my matches to upload their DNA files from other vendors for free to FamilyTreeDNA so that everyone has more information points to work with.

  2. Thanks for summarizing the offering from Genetic Affairs wrt the various DNA companies. This gets confusing.

    I just tried the Autocluster and auto tree feature on my FTDNA data. I got back an amazing amount of information. I liked the Cluster group data By chromosome, very useful.

    There also seemed to be a lot of shared location data by group. It will take me a while to look through all of this. I seemed to get less information on trees, maybe that is because my groups are small.
