World distribution of Y chromosome haplogroups

The major evolutionary lineages are depicted by the A to T nomenclature of the Y Chromosome Consortium, with the position of the identifiers corresponding to the geographic region where the haplogroup originated or where prevalence is high. Haplogroup P* due to its minimal distribution is not shown.

Arrows represent an abridged outlook into the major Y haplogroup migration events.

Red identifiers indicate the fixation of partial AZFc deletions in some of the lineages constituting the haplogroup. Their extensive dissemination suggests that partial AZFc deletions in these evolutionary backgrounds do not convey phenotypical consequences for male fertility.
