Y-DNA haplogroups by population. Y-DNA haplogroups in populations of the Caucasus; Y-DNA haplogroups in populations of South Asia; Y-DNA haplogroups in populations of East and Southeast Asia; Y-DNA haplogroups in populations of the Near East; Y-DNA haplogroups in populations of North Africa; Y-DNA haplogroups in populations of Europe
The haplogroups determined by Y-DNA and mtDNA tests are often unevenly geographically distributed. Many direct-to-consumer DNA tests described this association to infer the test-taker's ancestral homeland. [4] Most tests describe haplogroups according to their most frequently associated continent (e.g., a "European haplogroup"). [4]
Y-DNA haplogroup migration in East Asia. The tables below provide statistics on the human Y-chromosome DNA haplogroups most commonly found among ethnolinguistic groups and populations from East and South-East Asia .
The East Asian Y-chromosome haplogroup O-M122 is found in large quantities, about 24–30%, in other Muslims groups close to the Hui like the Dongxiangs, Bo'an, and Salar people. While the Y chromosome haplogroup R1a (found among Central Asians, South Asians and Europeans) are found among 17–28% of them. Western mtDNA makes up 6.6% to 8%.
The mitochondrial-DNA haplogroups of the Han Chinese can be classified into the Northern East Asian-dominating haplogroups, including A, C, D, G, M8, M9, and Z, and the Southern East Asian-dominating haplogroups, including B, F, M7, N*, and R. [141] These haplogroups account for 52.7% and 33.85% of those in the Northern Han, respectively.
(Data from studies conducted before 2004 may be inaccurate or a broad estimate, due to obsolete haplogroup naming systems – e.g. the former Haplogroup 2 included members of the relatively unrelated haplogroups known later as Haplogroup G and macrohaplogroup IJ [which comprises haplogroups I and J].)

Haplogroup A2 is the most common haplogroup among the Inuit, Na-Dene, and many Amerind ethnic groups of North and Central America. Lineages belonging to haplogroup A2 also comprise the majority of the mtDNA pool of the Inuit and their neighbors, the Chukchis, in northeasternmost Siberia. [5] [6] [7]
