Haplogroup O-M175
In molecular evolution, a haplogroup (from the (ギリシア語:ἁπλούς), ''haploûs'', "onefold, single, simple") is a group of similar haplotypes that share a common ancestor having the same single nucleotide polymorphism (SNP) mutation in all haplotypes. Haplogroup O-M175 is a Y-chromosome DNA haplogroup of Southeast Asian and East Asian lineage. It descends from Haplogroup NO.
==Origins==
Haplogroup O-M175 is a descendant haplogroup of Haplogroup NO-M214, and first appeared according to different theories, either in Southeast Asia (see , , , and ) or East Asia (see ) between 28,000 and 41,000 years before present according to or between 23,000 and 32,000 years before present according to Yan ''et al.'' 2013.〔Shi Yan, Chuan-Chao Wang, Hong-Xiang Zheng ''et al.'' (2013), "Y Chromosomes of 40% Chinese Are Descendants of Three Neolithic Super-grandfathers." E-print at arXiv:1310.3897 ().〕
Haplogroup O-M175 is one of NO-M214's two branches. The other is Haplogroup N, which is common throughout North Eurasia.
