"Interest in genetic testing to determine ancestry has increased rapidly since its introduction in 2000. Many individuals are eager to learn more about their ancestors, and believe genetic testing will be able to provide information where other traditional genealogical methods have failed. While genetic ancestry testing may in some cases be able to provide very general information, it also currently has many limitations. The very complex relationship between race, genetics, and ancestry further complicates this testing and the interpretation of results. Genetic ancestry testing may, therefore, raise several policy issues. This report describes genetic ancestry testing, outlines the basic scientific limitations of the testing currently, and provides an overview of the policy issues this testing may raise."
