Y-DNA haplogroups by ethnic group
Listed here are notable ethnic groups by Y-DNA haplogroups based on relevant studies. The data are presented in two columns for each haplogroup with the first being the sample size (n) and the second the percentage in the haplogroup designated by the column header. The samples are taken from individuals identified with the ethnic and linguistic designations in the first two columns. Some old studies conducted in the early 2000s regarded several haplogroups as one haplogrup, e.g. I, G and sometimes J were haplogroup 2, so conversion sometimes may lead to unsubstantial frequencies below.
The tree below shows the descent of the major Y Chromosomal groups from the so-called Y-Chromosomal Adam.
