Y-DNA

Y-DNA refers to the DNA found on the Y chromosome, which is one of the two sex chromosomes in humans—the other being the X chromosome. Only males have a Y chromosome, inherited from their father. Y-DNA is often used in genealogical and genetic studies to trace paternal lineage, as it remains relatively unchanged through generations. This makes it a valuable tool for understanding ancestry and familial relationships, particularly in studying the migration patterns of male ancestors. Testing Y-DNA can help individuals connect with their roots and discover more about their family history.
