Geographical distribution
Most research has tested only for the presence of R-M479 (R2) and R-M124 (R2a) – or SNPs downstream from M124 like P249, P267, L266, PAGES00004, and L381 SNPs). Because the other primary branch,
R2b (R-FGC21706) was discovered later than R2a, it has often not been tested for. Hence most results are best described as R2(xR2a).
In addition, relatively little research has been done within South Asia, which is known to have the greatest concentration of R2. (Hence the figures cited in the table right may not be indicative of true frequencies, i.e. Pakistan is the only South Asian country that has been included.)
In 2013, R2(xR2a) was found in 5 out of 19 males from the
Burusho minority of North Pakistan.
