R-M343
Haplogroup R1b (R-M343), previously known as Hg1 and Eu18, is a Human Y-chromosome DNA haplogroup, human Y-chromosome haplogroup. It is the most frequently occurring paternal lineage in Western Europe, as well as some parts of Russia (e.g. the Bashkirs) and pockets of Central Africa (e.g. parts of Chad and among the Chadic-speaking minority ethnic groups of Cameroon). The clade is also present at lower frequencies throughout Eastern Europe, Western Asia, as well as parts of North Africa, South Asia and Central Asia. R1b has two primary branches: R1b1-L754 and R1b2-PH155. R1b1-L754 has two major subclades: R1b1a1b-M269, which predominates in Western Europe, and R1b1b-V88, which is today common in parts of Central Africa. The other branch, R1b2-PH155, is so rare and widely dispersed that it is difficult to draw any conclusions about its origins. It has been found in Bahrain, India, Nepal, Bhutan, Ladakh, Tajikistan, Turkey, and Western China. According to ancient DNA studies, mo ...

Haplogroup R1
Haplogroup R1, or R-M173, is a Y-chromosome DNA haplogroup. A primary subclade of Haplogroup R (R-M207), it is defined by the SNP M173. The other primary subclade of Haplogroup R is Haplogroup R2 (R-M479). Males carrying R-M173 in modern populations appear to comprise two subclades: R1a and R1b, which are found mainly in populations native to Eurasia (except East and Southeast Asia). R-M173 contains the majority of representatives of haplogroup R in the form of its subclades, R1a and R1b (, , and ). Structure Origins The origins of haplogroup R1 remain unclear. It and its sibling clade R2 (R-M79) are the only immediate descendants of Haplogroup R (R-M207). R is a direct descendant of Haplogroup P1 (P-M45), and a sibling clade, therefore, of Haplogroup Q (Q-M242). No examples of the basal subclade, R1* have yet been identified in living individuals or ancient remains. However, the parent clade, R* was evidently present in upper paleolithic-era individuals (24,000 years ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
