Haplogroup K2, also known as K-M526 and formerly known as K(xLT) and MNOPS, is a human Y-DNA Haplogroup. Subclades of K2 are carried by males native to regions including: Oceania, South East Asia, East Asia, Central Asia, the Americas, Europe and South Asia. The only living males reported to carry the basal paragroup K2 * (K-M526) are indigenous Australians. Up to 27% of Aboriginal Australian males may carry K2 * and a further 29% appear to carry subclades within K2.〔 Nagle, N. et al., 2015, "Antiquity and diversity of aboriginal Australian Y-chromosomes", ''American Journal of Physical Anthropology'' (epub ahead of print version; (abstract )). (The authors assumed 56% of the samples taken to be non-indigenous.) 〕 〔Karafet 2014〕 The remains of Ust'-Ishim man, dating from approximately 45,000 BP and found in Omsk Oblast, Russia, also appear to belong to the paragroup K2 *.〔 ==Structure== (詳細はHaplogroup K, K2 is a sibling of basal/paragroup K * and Haplogroup LT (also known as K1). Haplogroup K2 is the direct ancestral haplogroup to five main descendant subclades: * Haplogroup NO M214/Page39 (also known as K2a); * Haplogroup K2b M1221/P331/PF5911, previously known as MPS * * the descendants of K2b include the major haplogroups M; S, P, Q, and R * K2c (P261) * K2d (P402) * K2e (M147) 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 K2」の詳細全文を読む スポンサード リンク
