Y-DNA haplogroups in populations of the Near East Y-DNA haplogroups in populations of the Near East Listed here are notable ethnic groups and populations from Western Asia, North Africa and South Caucasus by human Y-chromosome DNA haplogroups based on relevant studies. The samples are taken from individuals identified with the ethnic and linguistic designations in the first two columns, the third column gives the sample size studied, and the other columns give the percentage of the particular haplogroup. (IE = Indo-European, AA = Afro-Asiatic) 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
