Rather than find matches in genetic genealogy databases (we’d love to see that utility), these free tools help you learn more about your DNA test results. Three of the tools work using data from the FamilyTreeDNA Web site, so customers of other companies will have to pass on those. The tools include:
- FamilyTreeDNA Markers: Use this one to view your Y-chromosome test results from FamilyTreeDNA—just enter your kit and code numbers.
- Haplogroups: Anyone who’s taken a Y-DNA test can get a pretty good idea of his haplogroup by entering his STR marker values. (If you’re a FamilyTreeDNA client, just enter your kit and code number.) As Morse explains, haplogroups are defined by SNP markers, but you usually don’t get SNP values in a Y-DNA test report. STR marker values, though, can predict a haplogroup.
- Group Chart: Here, you can generate a DNA chart for a group of people for easier test results comparison. Each group member must have tested with FamilyTreeDNA.
- Distances: FamilyTreeDNA clients can use their group chart (generated with the Group Chart tool) to compute the genetic distances among members of the group.
- Migration Details: Select your haplogroup from a dropdown menu to get a description of your ancient ancestors’ migrations across the globe. You’ll see shifts in haplogroups and the mutation numbers that defined the shifts, along with the geographic location and time range the mutation took place.
- Migration Map: Select your haplogroup to generate a visual representation of the migration details described above.
See the DNA toolkit on FamilyTreeMagazine.com for genetic genealogy advice, explanations and resources.
Steve Morse also has created One-Step Tools for searching online databases such as EllisIsland.org and Ancestry.com (you must subscribe to Ancestry.com to see search results from its databases). You’ll find hints for using the tools in the February 2007 Family Tree Magazine.
