Understanding Genetic Genealogy

Genetic genealogy is a type of genealogical research that uses DNA testing to establish familial relationships and trace ancestry. DNA ancestry testing involves a comparison of an individual’s DNA with that of others in a database to determine shared genetic markers.

Genealogy genetic testing is typically conducted through a saliva or cheek swab sample, which is sent to a laboratory for analysis. The results are then presented in a report detailing the individual’s genetic ancestry and any potential matches with other individuals in the database.

How Genetic Genealogy Works

Genetic genealogy works by analyzing specific DNA markers passed down through generations to identify shared ancestry. These markers can be found in autosomal DNA, mitochondrial DNA, and Y-chromosome DNA.

Autosomal DNA testingMitochondrial DNA testingY-chromosome DNA testing
Looks at DNA inherited from both parentsLooks at DNA passed down from mother to childLooks at DNA passed down from father to son
Can identify relatives up to six generations backCan identify maternal lineage up to thousands of years backCan identify paternal lineage up to thousands of years back

By analyzing these markers, genetic genealogy can provide information on an individual’s ethnicity, geographic origins, and familial connections. It can also uncover unknown relatives and confirm or disprove existing genealogical research.
