Y-DNA haplogroup clade finder
Upload your raw DNA file from 23andMe, AncestryDNA, MyHeritage or a VCF and find your Y-chromosome haplogroup — your paternal-line branch on the human family tree — plus a map of ancient men who shared it.

How a paternal haplogroup is read from a consumer file
The Y chromosome passes from father to son almost unchanged, so the mutations it carries accumulate in a single line and define a branching tree. Placing you on that tree means reading which known branch-defining variants your file calls in the derived state and finding the deepest branch all of them agree on. This tool reads the Y-chromosome rows out of a 23andMe, AncestryDNA, MyHeritage or VCF export, compares them against the published tree, and reports the clade you reach along with the variants that put you there.
Your paternal haplogroup is a line, not an ethnicity. It traces one path through your ancestry — your father's father's father — and says nothing about the rest of your genome, which is where almost all of your ancestry lives. Two people can share a haplogroup and differ everywhere else, and siblings of different sexes do not both carry one.
The hard limit is coverage. Consumer chips genotype a sparse, fixed set of Y positions chosen years ago, so the depth you can reach is set by which markers your file happens to contain rather than by your actual lineage. A shallow result usually means the file lacks the markers that would resolve further, not that your line stops there — and where the evidence thins out, the result says so instead of guessing at a deeper branch. Only sequencing reads the whole chromosome. Runs need a free, email-verified account, and the uploaded file is deleted after the analysis.
