Talk:Haplogroup G (Y-DNA)

From Wikipedia, the free encyclopedia

The statement about G being brought to Europe by Iranians is debatable; Indians, the descendants of ancient Aryans, show no presence of G and the high percentage of G in Ossetians is thus very probably only a result of the Caucasian influence and a genetic drift. 82.100.61.114 00:09, 17 March 2007 (UTC)

Haplogroup G is found among Aryans (Pakistanis and Indians), although at low frequency. It is even found in China, Malaysia, and parts of Oceania, especially the Malay Archipelago. This article on Balinese paternal heritage tabulates some samples from India, Malaysia, and China that belong to Haplogroup G. In Central Asia, Haplogroup G is found as far east as among the Mongols. The range of its distribution should not be underestimated; Haplogroup G just doesn't receive much attention because of its very low frequency among most modern populations outside of the Caucasus. That study that I linked to is very comprehensive; the researchers examined 1,989 Y-chromosomes that had been sampled from 20 populations of Southwest Asia, South Asia, Southeast Asia, Oceania, and Southern China and found a total of only 18 Haplogroup G-M201 Y-chromosomes, including 2 out of 32 Malaysians (6.25% of the Malaysian sample), 1 out of 166 Han Chinese (0.6%), 6 out of 405 Indians (1.5%), 5 out of 91 Sri Lankans (5.5%), 1 out of 22 Saudi Arabians (4.5%), and 3 out of 87 Syrians (3.4%). When one considers the tremendous size of the Indian population, it is easy to see the possibility that the Iran-Afghanistan-Pakistan-India belt (precisely the region of the "Aryans") probably contains the greatest number of Haplogroup G persons in the world.
