How to Test DNA for Genealogical Purposes

Example of a family tree

DNA can be a valuable tool when doing genealogical research on a family, as exact matches of the Y-chromosome can indicate familial relationships within five generations. If one or two genetic markers are found to be different, then the two people are not directly related and may have a distant connection at best. Y-chromosome tests can also indicate clan relationships and can connect a family tree back to a distant ancestor. According to the website Ancestry.com, Y-chromosomal DNA tests have proven to be more useful for geneological testing than mitochondrial DNA (female) tests. DNA tests for genealogical purposes are available online or through a doctor's office.

Things You'll Need

• DNA kit

Instructions

1. Note that only males can take a Y-chromosome DNA test. However, females may request that a brother, father, paternal nephew or paternal uncle to take the test.

2. Take one of the sterile swabs that is included in the DNA test. Gently swab the inside of your cheek. Roll the swab around thoroughly but do not push too hard, as this is not necessary to collect genetic material.

3. Place the swab in the envelope provided with the DNA kit.

4. Sign the consent form that is provided with the DNA test. Place the consent form and swab envelope in the return envelope. Close securely and place in the mail.

5. Note that results take about six weeks to be returned. Once you have your DNA results, you can begin to search your genealogical background through your local library, online resources, or websites such as Ancestry.com.
