Haplogroup B-M60 (Y-DNA) : ウィキペディア英語版
Haplogroup B-M60

In human population genetics, haplogroups define the major lineages of direct paternal (male) lines back to a shared common ancestor. Haplogroup B (B-M60) is a Y-chromosome haplogroup common to paternal lineages in Africa, in Arabian Peninsula and in Eurasia.
==Distribution==
Haplogroup B-M60 is found in sub-Saharan Africa, especially to tropical forests of West-Central Africa. After Y-haplogroup A, it is the second oldest and one of the most diverse human Y-haplogroups. It was the ancestral haplogroup of not only modern Pygmies like the Baka and Mbuti, but also Hadzabe from Tanzania, who often have been considered, in large part because of some typological features of their language, to be a remnant of Khoisan people in East Africa.
According to one study of the Y-DNA of populations in Sudan, haplogroup B-M60 is found in approximately 30% (16/53) of Southern Sudanese, 16% (5/32) of local Hausa people, 14% (4/28) of the Nuba of central Sudan, 3.7% (8/216) of Northern Sudanese (but only among Copts and Nubians), and 2.2% (2/90) of Western Sudanese.〔Hisham Y. Hassan, Peter A. Underhill, Luca L. Cavalli-Sforza, and Muntaser E. Ibrahim, "Y-Chromosome Variation Among Sudanese: Restricted Gene Flow, Concordance With Language, Geography, and History," American Journal of Physical Anthropology (2008).〕 According to another study, haplogroup B is found in approximately 15% of Sudanese males, including 12.5% (5/40) B2a1a-M109/M152 and 2.5% (1/40) B-M60(xM146, M150, M112).〔
In Madagascar, haplogroup B-M60 has been found in approximately 9% of Malagasy males, including 6% (2/35) B-M60(xB2b-50f2(P)) and 3% (1/35) B2b-50f2(P).〔
In Hormozgan Province in Iran, haplogroup B-M60 has been found in 8.2% of a sample of 49 Qeshmi people, and in 2.3% of a sample of 131 Bandari people.〔(Viola Grugni, Vincenza Battaglia, Baharak Hooshiar Kashani, Silvia Parolo, Nadia Al-Zahery, et al. "Ancient Migratory Events in the Middle East : New Clues from the Y-Chromosome Variation of Modern Iranians", 2012 )〕
In Afghanistan, haplogroup B-M60 has been found in 5.1% (3/59) of a sample of Hazara males.〔(Haber M, Platt DE, Ashrafian Bonab M, Youhanna SC, Soria-Hernanz DF, et al. "Afghanistan's Ethnic Groups Share a Y-Chromosomal Heritage Structured by Historical Events", 2012 )〕
In United Kingdom, haplogroup B-M60(xM218) has been found by (FTDNA ) in 1 individual.
