Mitochondrial DNA (mtDNA), inherited solely through the maternal line, allows genealogists to trace ancestry back tens of thousands of years. Its passed unchanged from mother to child, making it a powerful tool for studying ancient migrations, like the spread of haplogroup H across Europe 20,000 years ago. MtDNA testing can connect people to prehistoric populations or confirm maternal lineage, though its limited to direct female lines. Companies like FamilyTreeDNA specialize in mtDNA analysis for genealogy.
