, a family history networking Web site where members can create profiles and explore their genetic genealogy, just added Y-DNA testing to its offerings.
A 33-marker test and a 46-marker test are available; prices start at $149 with discounts for those who’ve already ordered a mitochondrial DNA test through GeneTree.
Since men pass their Y-DNA to sons along with (usually) their surname, Y-DNA testing is helpful for confirming or disproving relationships between individuals with the same last name.
Y-DNA test-takers also can participate in surname studies (which GeneTree president Matt Cupal says the company will kick off in the near future) and enter test results in Y-DNA databases to look for matches.
Women—who don’t have Y-DNA—can participate by having a father, brother or male-line cousin or uncle take a test. For example, your father’s brother or the brother’s son could take a Y-DNA test and the results would apply to you.
Cupal says even though Y-DNA tests are more-used, GeneTree launched with mitochondrial DNA services because they apply to both men and women. (Women pass mitochondrial DNA to their offspring.)
The Sorenson Molecular Genealogy Foundation, whose mitochondrial DNA database you can search using GeneTree’s DNAvigator tool, also has amassed more mitochondrial- than Y-DNA results.
Right now DNAvigator searches 51,000 of SMGF’s 72,000 mitochondrial DNA results; that number will be increased in the coming month. Eventually, a new version of the DNAvigator will search both mitochondrial- and Y-DNA results.
Cupal says GeneTree has more than half a million profiles, which includes both living members and their ancestors.
