Haplogroup R-FGC21706

Haplogroup R2b, or R-FGC21706/R-FGC50231, is a Y-chromosome haplogroup characterized by genetic marker FGC21706/FGC50231. It is one of two primary descendants of Haplogroup R2 (R-M479), one being R2a (R-M124) and the other being the aforementioned R2b.

R2b and its origin are not very well known, due to the extremely low number of testers who are positive for this SNP^[1], (29/2349 testers on FTDNA are positive for R2b out of the total R2 positive population).

Of the R2b individuals tested, the countries with the highest proportion of testers who are positive for R2b (as opposed to all testers in each respective country), include Pakistan, Tajikistan and Afghanistan, with 2% of testers hailing from Pakistan, 0.6% from Tajikistan, 0.4% from Afghanistan, 0.2% from India, 0.1% from Bahrain and <0.1% in both Saudi Arabia and Iraq^[2]
