AncestrybyDNA™ tests are performed to determine an individual's bio-geographic ancestry. Whether you're interested in researching your family history, or just simply want to learn more about yourself, this test can provide you with a better understanding of your genetic ancestry and provide a window into further research about your possible ancestors.
How accurate is the AncestrybyDNA™ test?
The AncestrybyDNA™ test provides your ancestral proportions based on years of collaborative research of populations representing 4 ancestral groups. This research identified 176 informative markers in our DNA, called Ancestry Informative Markers (AIMs).
The results typically give you a 95% confidence interval, which is a measure of the statistical strength of the test. The only way to achieve 100% accuracy in an ancestry test would be to go back in time and test each and every one of your ancestors. Since this is impossible, they rely on statistics to make a prediction of your most likely ancestry mix.
The scientists who developed the Ancestryby™DNA test have conducted extensive validation studies with various numbers of markers to create a test that was economically feasible as well as provides the most robust statistical data. The first version of the test used 71 markers—today we test 176 markers to obtain a much higher confidence level while keeping costs to a minimum. In a validation study that used a simulated 100% European population, for example, the test results showed less than 3.3% of total average contribution from African, Indigenous American, and East Asian ancestry, indicating the level of "statistical noise" that is to be expected from the results.
Paternal Lineage (Y-STR) Testing
This type of DNA testing determines what migration routes your ancient paternal ancestors took.
Paternal Lineage (Y-STR) Testing™ relies on portions of human DNA that are passed from father to child relatively unchanged through many generations. One could say that by examining these key parts of our DNA, our paternal history could be traced as far back as the first peoples who populated the earth. Scientific data shows that modern humans evolved in Africa 400,000 to 130,000 years ago, and started migrating outward.
Maternal Lineage (mtDNA) Testing
This type of DNA testing determines what migration routes your ancient maternal ancestors took.
