Understanding DNA Tests and Our Science.
Deoxyribonucleic acid (DNA) is the biological material that contains the blueprint and instructions for all function and development of living organisms. By examining and analyzing DNA, we can compare your genes to those of millions of people all over the planet. DNA analysis can be used for many purposes; we use it to provide genealogical information about your ancestry.
The DNA Fingerprint Test will analyze your DNA sample against 16 standard STR markers, also called CODIS markers. (CODIS stands for Combined DNA Index System, and it probably sounds familiar if you watch any of television’s popular procedural crime shows like CSI.) You can learn more about CODIS at the FBI website.
CODIS markers are also used in relationship testing such as paternity tests. See what samples can be used.
Other tests look for different markers in your DNA. The Premium Male determines 43 marker values or alleles in your Y chromosome (provided you are a male). The Premium Female establishes the mutations in two control regions of the mitochondrial DNA passed to you by your mother. Learn more about Male, Female and Combo tests.
In the past, using DNA to research one’s ancestry was dependent on which gender of relative was available to test, and then the results were confined to just the “outside” male-male or female-female lines. Today, there are other options, including the ability to test one’s entire genome, regardless of gender. Genome-wide testing with the DNA Fingerprint Test reflects your entire ancestry.
There are many tests available but which one to take will depend on your particular research goals. Take our DNA Wizard Quiz to learn which products are right for you.
The DNA Fingerprint Test: The Great Equalizer
The geneticists at our laboratories are some of the best in the world. But, we don’t stop at the list of numbers produced by the lab work.
Our staff members are degreed professionals in history, philology and the social sciences, and they can translate your number sets into a meaningful historical story, based on extensive knowledge of world history, population studies and genealogy sources. Your DNA analysis will be customized for your personal research goals. This creates a superior ancestry research experience – with a report that you can actually read and understand.
We rely on DNA Diagnostics Center of Fairfield, Ohio, for processing of DNA profiles for our autosomal products, including the DNA Fingerprint Test and DNA Fingerprint Plus, as well as for performing our Y-chromosome and mitochondrial tests.
