MTDNA G - DNAGENICS

It is an East Asian haplogroup. Today, haplogroup G is found at its highest frequency in indigenous populations of the lands surrounding the Sea of Okhotsk. Haplogroup G is one of the most common mtDNA haplogroups among modern Ainu, Japanese, Mongol, and Tibetan people (as well as among people of the prehistoric Jōmon culture in Hokkaidō). It is also found at a lower frequency among many other populations of East Asia, Central Asia, Bangladesh, Sri Lanka, and Nepal. However, unlike other mitochondrial DNA haplogroups typical of populations of northeastern Asia, such as haplogroup A, haplogroup C, and haplogroup D, haplogroup G has not been found among indigenous peoples of the Americas.
