R2

Background

Family Tree DNA's haplogroup description of R2: Haplogroup R2 originated in South Asia and is generally found in Central Asia, Turkey, Pakistan, and India. Wikipedia's Haplogroup R2 R2 SCIENTIFIC STUDIES DATA Polarity and Temporality of High-Resolution Y-Chromosome Distributions in India Identify Both Indigenous and Exogenous Expansions and Reveal Minor Genetic Influence of Central Asian Pastoralists by S. Sengupta, et al. EXCERPT:"The decreasing frequency of R2—from 7.4% in Pakistan to 3.8% in Central Asia (Wells et al. 2001) to 1% in Turkey (Cinnioglu et al. 2004)—is consistent with the pattern observed for the autochthonous Indian H1-M52 HG"[pg 9]...."The distribution of R1a1 and R2 within India is similar, as are the levels of associated microsatellite variance (table 12). The ages of the Y-microsatellite variation (table 11) for R1a1 and R2 in India suggest that the prehistoric context of these HGs will likely be complex." [pg 17] 2005
