Haplogroup G is believed to have originated 14 to 30 kya
in the Middle East or South Asia. Its defining SNP is M201.
Its parent is F (characterized by a long list of SNPs).
Its children are subclades G1 (SNPs: M285, M342) & G2 (SNP: P287) .
Haplogroup G is believed to have been brought to Europe by Neolithic Age
farmers and herders as early as 9 kya. It is the haplogroup of Otzi the
Iceman, whose mummified body was found in an alpine glacier. Other ancient
European remains are also haplogroup G.
"The haplogroup is the most frequent in the Caucasus (found at over 60% in ethnic
North Ossetian males and around 30% in Georgian males). The
Kabardinian and Balkarian peoples of the northwestern Caucasus are known to
be 29% G.
Armenians are known to have around 11% of their males in Hg G."
The article goes on to say that the haplogroup in found in frequencies of
about 5% to 10% in other parts of Europe, but lower in Britain & Norway. About
10% of Ashkenazi Jewish males are Hg G. In Southwest Asia, frequencies rise
to as much as 20%.
