Haplogroup HIJK, defined by the SNPs F929, M578, PF3494 and S6397,〔(ISOGG, 2015, ''Y-DNA Haplogroup Tree 2015'' ) (8 September 2015).〕 is a common Y-chromosome haplogroup. Like its parent macrohaplogroup GHIJK, Haplogroup HIJK and its subclades comprise the vast majority of the world's male population. HIJK branches subsequently into two direct descendants: IJK (L15/M523/PF3492/S137) and H (L901/M2939). IJK in turn splits into IJ (F-L15) and K (M9). The descendants of Haplogroup IJ are haplogroups I and J, while Haplogroup K is, ultimately, the ancestor of major haplogroups M, N, O, P, Q, R, S, L, and T. ==Distribution== Populations with high proportions of males who belong to descendant major haplogroups of Haplogroup HIJK live across widely-dispersed areas and populations. South Asia was where Haplogroup H (L901/M2939) almost certainly originated, and became concentrated before the mass migrations of the modern era. South Asia was also where two haplogroups descended ultimately from IJK (L15/M523/PF3492/S137) remained concentrated and/or prominent, namely Haplogroups L and R. Males belonging to other subclades of IJK are concentrated in: * Europe (e. g. haplogroups I, R and N); * the Middle East and North East Africa (e. g. haplogroups J and T); * South East Asia and many Pacific Islands (e. g. haplogroups K, M, O, P, S) * northern Eurasia (e. g. haplogroups N and Q) and; * many Native American peoples (e. g. haplogroup Q) outside Alaska and Western Canada. 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 HIJK」の詳細全文を読む スポンサード リンク
