Y-DNA testing

Y-DNA testing analyzes the genetic material in a man's Y chromosome, which is passed directly from father to son. This type of testing helps trace paternal ancestry and determine relatedness within male lines, as the Y chromosome remains relatively unchanged over generations. By examining specific markers on the Y chromosome, it can identify common ancestors, establish family connections, and explore geographic or ethnic origins. Y-DNA testing is a valuable tool for genealogical research, forensic investigations, and understanding paternal lineage, providing insights into a man's direct paternal heritage.
