Haplogroup O2 (Y-DNA)
Haplogroup O-M268 (former name) is a Y-DNA that descends from O1 (O-F265), however, it is now referred to as O1b. Origin The authors of a study published in 2011 have suggested China as being the early birthplace of O1b.Shi Yan, Chuan-Chao Wang, Hui Li, Shi-Lin Li, Li Jin, and The Genographic Consortium, "An updated tree of Y-chromosome Haplogroup O and revised phylogenetic positions of mutations P164 and PK4." ''European Journal of Human Genetics'' (2011) 19, 1013–1015; doi:10.1038/ejhg.2011.64 Other studies suggest a complex origin that is inconclusive because of rising seawater to the east of China (which may have been a walkable land mass). Despite such studies, descendants of O1b suggest two primary migration paths from Southeast China: * Korea & Japan * Southeast Asia This suggestion aims to draw an intersection to support the theory of both migration paths being in opposite spectrums geographically in East Asia. There has also beerecent suggestionsthat Korea play ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southeast Asia
Southeast Asia is the geographical United Nations geoscheme for Asia#South-eastern Asia, southeastern region of Asia, consisting of the regions that are situated south of China, east of the Indian subcontinent, and northwest of the Mainland Australia, Australian mainland, which is part of Oceania. Southeast Asia is bordered to the north by East Asia, to the west by South Asia and the Bay of Bengal, to the east by Oceania and the Pacific Ocean, and to the south by Australia (continent), Australia and the Indian Ocean. Apart from the British Indian Ocean Territory and two out of Atolls of the Maldives, 26 atolls of the Maldives in South Asia, Maritime Southeast Asia is the only other subregion of Asia that lies partly within the Southern Hemisphere. Mainland Southeast Asia is entirely in the Northern Hemisphere. Timor-Leste and the southern portion of Indonesia are the parts of Southeast Asia that lie south of the equator. The region lies near the intersection of Plate tectonics, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haplogroup O-M50 (Y-DNA)
A haplotype is a group of alleles in an organism that are inherited together from a single parent, and a haplogroup (haploid from the , ''haploûs'', "onefold, simple" and ) is a group of similar haplotypes that share a common ancestor with a single-nucleotide polymorphism mutation. More specifically, a haplotype is a combination of alleles at different chromosomal regions that are closely linked and tend to be inherited together. As a haplogroup consists of similar haplotypes, it is usually possible to predict a haplogroup from haplotypes. Haplogroups pertain to a single line of descent. As such, membership of a haplogroup, by any individual, relies on a relatively small proportion of the genetic material possessed by that individual. Each haplogroup originates from, and remains part of, a preceding single haplogroup (or paragroup). As such, any related group of haplogroups may be precisely modelled as a nested hierarchy, in which each set (haplogroup) is also a subset of a sing ...

Haplogroup O-M117 (Y-DNA)
Haplogroup O2a2b1a1-M117 or Haplogroup O2a2b1a1-M117 (also defined by the phylogenetically equivalent mutation Page23/F8/F42) is a subclade of O2a2b1-M134 (and also a subclade of haplogroup O2-M122) that occurs frequently in China and in neighboring countries like Bhutan, Nepal, and Korea, also found among Sino-Tibetan language speaking people. O2-M117 has been detected in samples of Tamang (38/45 = 84.4%), Tibetans (45/156 = 28.8% or 13/35 = 37.1%), Tharus (57/171 = 33.3%), Han Taiwanese (40/183 = 21.9%), Newars (14/66 = 21.2%), the general population of Kathmandu, Nepal (13/77 = 16.9%), Han Chinese (5/34 = 14.7% Chengdu, 5/35 = 14.3% Harbin, 4/35 = 11.4% Meixian, 3/30 = 10.0% Lanzhou, 2/32 = 6.3% Yili), Tungusic peoples from the PRC (7/45 = 15.6% Hezhe, 4/26 = 15.4% Evenki, 5/35 = 14.3% Manchu, 2/41 = 4.9% Xibe, 1/31 = 3.2% Oroqen), and Uyghurs (2/39 = 5.1% Yili, 1/31 = 3.2% Ürümqi) (Xue et al. 2006, Gayden et al. 2007, and Fornarino et al. 2009).

Haplogroup O-M7 (Y-DNA)
Haplogroup O-M122 (also known as Haplogroup O2 (formerly Haplogroup O3)) is an Eastern Eurasian Y-chromosome haplogroup. The lineage ranges across Southeast Asia and East Asia, where it dominates the paternal lineages with extremely high frequencies. It is also significantly present in Central Asia, especially among the Naiman tribe of Kazakhs. This lineage is a descendant haplogroup of haplogroup O-M175. Origins Researchers believe that O-M122 first appeared in Southeast Asia approximately 25,000-30,000 years ago, or roughly between 30,000 and 35,000 years ago according to more recent studies. In a systematic sampling and genetic screening of an East Asian–specific Y-chromosome haplogroup (O-M122) in 2,332 individuals from diverse East Asian populations, results indicate that the O-M122 lineage is dominant in East Asian populations, with an average frequency of 44.3%. Microsatellite data show that the O-M122 haplotypes are more diverse in Southeast Asia than those in north ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
