Y-DNA haplogroups in populations of Europe

Y-DNA haplogroups in populations of Europe are haplogroups of the male Y-chromosome found in European populations.

Frequencies in European ethnic groups
The table below shows the human Y-chromosome DNA haplogroups, based on relevant studies, for various ethnic and other notable groups from Europe. The samples are taken from individuals identified with the ethnic and linguistic designations shown in the first two columns; the third column gives the sample size studied; and the other columns give the percentage for each particular haplogroup (ethnic groups from the North Caucasus, although technically located in Europe, are considered in their own article where they are placed alongside populations of the South Caucasus for the purpose of conserving space).

Note: The converted frequency of Haplogroup 2, including modern haplogroups I, G and sometimes J from some old studies conducted before 2004 may lead to unsubstantial frequencies below.
