What is a Y Chromosome DNA Testing?

A Y Chromosome DNA Test is a relationship test that compares the Y chromosome between two males to determine a biological relationship.

The Benefits of Y-DNA Testing for Understanding Your Family History

Y-DNA testing is a powerful tool for understanding and determining a common paternal family history/lineage. By testing the Y-chromosome, which is passed down from father to son, you can trace your direct paternal line back in time. This can be especially helpful if you have a common surname, as it can help you connect with other people who share your surname and ancestor.
