In human genetics, Haplogroup H (Y-DNA), also known as H-L901/M2939 is a Y-chromosome haplogroup. This haplogroup is found at high frequencies among some populations in South Asia, particularly the subclade H1 (H-M69), including its direct descendant H1a (M52). Outside South Asia, H1a1 (H-M82) – which is a direct descendant of H1A/M-82 – is found commonly in the paternal lineage of Romani people in Europe. H2 (P96) was found in Neolithic Iberia〔(Ancient Genomes link early farmers from Atapuerca in Spain to modern-day Basques, 2015, Torsten Günther )〕〔(Ancient genomes link of early farmers, 2015, Cristina Valdiosera )〕 and has somewhat of a concentration in Western Europe, but it is also found in Armenian, Iran, and India. ==Structure== H-L901/M2939 is a direct descendant of Haplogroup GHIJK. There are, in turn, three direct descendants of H-L901/M2939 – their defining SNPs are as follows: * H1: M69/Page45, M370; - South Asians, Romani and Tajiks * H2: P96, L279, L281, L284, L285, L286, M282 (formerly known as H * and before that misclassified under Haplogroup F-M89, as "F3");〔()〕 - Western Europe: in France, Switzerland, Germany and the Netherlands. But it is also found in Armenian, Iran, and India. H2 was found in Nelothic Iberia〔 http://www.pnas.org/content/suppl/2015/09/02/1509851112.DCSupplemental/pnas.1509851112.sapp.pdf〕〔 http://www.pnas.org/content/112/38/11917.full.pdf〕 * H3: Z5857 - South Asians 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Haplogroup H (Y-DNA)」の詳細全文を読む スポンサード リンク
