Haplogroup C2 M217, previously known as C3,〔 is a Y-chromosome DNA haplogroup. It is the most frequently occurring branch of the wider Haplogroup C (M130). M217 is found at high frequencies among Central Asian peoples, indigenous Siberians, and some Native peoples of North America. In particular, males belonging to peoples such as the Buryats, Evens, Evenks, Kazakhs, Mongolians and Udegeys have high levels of M217.〔 〔〔 One particular haplotype within Haplogroup C2 M217 has received a great deal of attention for the possibility that it may represent direct patrilineal descent from Genghis Khan.〔 (as PDF )〕 The more convincing explanation is that it was originated from one of many mongolic tribes. ==Origin== Haplogroup C-M217 is believed to have originated approximately 7,100 to 16,700 years before present〔 in eastern or central Asia. Its closest phylogenetic relatives are found in the general vicinity of South Asia, East Asia, or Oceania. The extremely broad distribution of Haplogroup C-M217 Y-chromosomes, coupled with the fact that the ancestral paragroup C is not found among any of the modern Siberian or North American populations among whom Haplogroup C-M217 predominates, makes the determination of the geographical origin of the defining M217 mutation exceedingly difficult. The presence of Haplogroup C-M217 at a low frequency but relatively high diversity throughout East Asia and parts of Southeast Asia makes that region one likely source. In addition, the C-M217 haplotypes found with high frequency among North Asian populations appear to belong to a different genealogical branch from the C-M217 haplotypes found with low frequency among East and Southeast Asians, which suggests that the marginal presence of C-M217 among modern East and Southeast Asian populations may not be due to recent admixture from Northeast or Central Asia.〔 (as PDF )〕 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 C-M217」の詳細全文を読む スポンサード リンク
