can dna be traced to sex of ancestor?
Your direct paternal lineage is the line that follows your fatherâs paternal ancestry. This line consists entirely of men. Y-DNA follows the direct paternal line. Your Y-chromosome DNA (Y-DNA) can trace your father, his father, his fatherâs father, and so forth. It offers a clear path from you to a known, or likely, direct paternal ancestor. Your Y-DNA may help you find genetic cousins along your direct paternal line.
