User:JohnLloydScharf/DNA for Ethnic Groups

Listed here are notable ethnic groups by Y-DNA haplogroups based on relevant studies. The data is 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.

The tree below shows the descent of the major Y Chromosomal groups from the so-called Y-Chromosomal Adam.
