Y-DNA haplogroups by ethnic group

The various ethnolinguistic groups found in the Caucasus, Central Asia, Europe, the Middle East, North Africa and/or South Asia demonstrate differing rates of particular Y-DNA haplogroups.
In the table below, the first two columns identify ethnolinguistic groups. Subsequent columns represent the sample size ("n") of the study or studies cited, and the percentage of each haplogroup found in that particular sample.
