Trace Your DNA's Genealogy

In April of 2000, FamilyTreeDNA.com began offering DNA genealogy tests. Since that time, they have continued to refine the process and claim that 90% of genealogists choose Family Tree DNA. This company works in coordination with a scientific board and the University of Arizona Research Labs. The research labs at the University of Arizona are run by one of the top genetics specialists in the world. FamilyTreeDNA.com has the largest genetic genealogy database so that when you receive your findings, you can use their database as a reliable source of information.

Male and Female DNA Tests

There are separate tests for males and females. The female test is known as the MITOCHONDRIAL – MTDNA test. This test will allow you to trace back your matrilineal family line through your mother, as the woman always gives an X chromosome. Both males and females can take this test because everyone has an X chromosome containing mitochondrial DNA.

The other test is exclusively for males and is known as a paternal test. Only males can take this test because it relies on genes found on the Y chromosome. The results of the paternal test can tell you the ethnic and geographic origin of the paternal line. It also provides a balanced panel of the amount of Y-chromosome Short Tandem Repeat (STR) markers that you’re willing to pay for. The more STR markers, the more expensive the test will be, but also, the more accurate. For example, if you test 12 markers, ten people might match up, but if you test 67 markers, you may only have one person match – and the chances that individual is your relative is significantly higher.

The DNA Process

You will be provided with all the tools you need in the DNA kit when you order it from Family Tree DNA or any other vendor you may select. You essentially use swabs to scrape the inside of your cheek and store the results in tubes that are provided for you. For fuller information, click here. You then send your DNA in to the lab and the lab will perform the analysis.

After your DNA is analyzed, the vendor will publish the results in their database and send you a copy. Based upon this information, you can analyze their database to see if your DNA matches the markers of others. When you are selecting a vendor for this process, keep in mind that the larger the database the vendor has, the more likely you can find a relative.
