Y-chromosomal lineage

Y-chromosomal lineage refers to the genetic heritage carried specifically on the Y chromosome, which is passed from father to son unchanged through generations. It helps trace paternal ancestry and migration patterns over thousands of years. By analyzing variations in the Y chromosome among individuals and populations, scientists can identify common ancestors and understand how populations have moved and evolved. This information provides insights into human history, kinship, and genetic diversity, making Y-chromosomal lineage a valuable tool in anthropology and genealogy.
