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.
Article: AutoClustering by Genetic Affairs
This article explains the basics of AutoClustering of matches and how autoclusters benefit genealogy.
- AutoClustering through Genetic Affairs can be used on tests at Family Tree DNA and 23andMe.
- AutoClustering is integrated for all users at MyHeritage. You can transfer your DNA file to MyHeritage if you have not tested there.
- Autoclustering is available at GedMatch under the Tier 1 level tools.
- Autoclustering is no longer available at Ancestry due to the cease-and-desist order issued by Ancestry.
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.
- AutoTree and AutoPedigree can only be used with results at Family Tree DNA, but not at any of the other vendors. You can transfer your DNA files from other testing companies to FamilyTreeDNA if you have not tested there.
- 23andMe does not support trees.
- Ancestry has issued a cease-and-desist order against Genetic Affairs.
- MyHeritage includes AutoClustering by Genetic Affairs within their product offering, but not AutoTree and AutoPedigree.
AutoPedigree + WATO
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.
I receive a small contribution when you click on some of the links to vendors in my articles. This does NOT increase the price you pay but helps me to keep the lights on and this informational blog free for everyone. Please click on the links in the articles or to the vendors below if you are purchasing products or DNA testing.
Thank you so much.
