Haplogroup Explorer
Track Y-DNA and mtDNA haplogroups across 32,000+ ancient DNA samples with interactive maps and timelines.
How it works: Enter a Y-DNA or mtDNA haplogroup (e.g., R1b, J2, H1, U5a) or a SNP name (e.g., M269, R-L21, I-Z2040). The tool searches our database of 32,000+ ancient DNA samples and displays matching samples on a map with a chronological timeline showing the haplogroup's spread through history.
📚 Ancient DNA reference data curated by GenArchivist (Nomad), the primary source for sample haplogroup assignments and annotations in this database.
Want a definitive answer on your own haplogroups? FamilyTreeDNA lineage tests
Consumer autosomal chips only read a few thousand Y and mitochondrial markers, so a haplogroup predicted from a raw file stays approximate. Dedicated lineage tests from FamilyTreeDNA sequence those lines fully.
Big Y-700
The most complete Y-chromosome test: your exact paternal haplogroup on the finest branch of the Y tree, back to prehistory.

Your complete mitochondrial genome: a definitive maternal haplogroup and matches along the direct maternal line.
View on FamilyTreeDNA →Y-DNA tests follow the direct father-to-son line, so they are for men. Women can ask their father, a brother or a paternal uncle to test. mtFull Sequence works for everyone.
