Ancestry.com launched a beta version of AncestryDNA, a new and potentially powerful genealogical DNA test, earlier this year, joining a handful of businesses offering autosomal DNA testing for ancestry research.
AncestryDNA’s analysis tools let you explore your test results. The Genetic Ethnicity tool uses the results to estimate the percentage of your DNA that is derived from certain geographic regions around the world (called “admixture”). The tool is based on genetic information taken from approximately 22 world regions and stored in proprietary and public databases.
Researchers have expressed concerns over the quality of family trees on Ancestry.com, and fear that wrong information will point to incorrect sources of shared DNA. But it’s possible that the combination of DNA and traditional genealogical records will help identify and correct these errors. Our ancestors’ DNA traveled far and is infinitely more powerful than the mistakes in our paper trails.
