The mitochondrial-DNA haplogroups of the Han Chinese can be classified into the Northern East Asian-dominating haplogroups, including A, C, D, G, M8, M9, and Z, and the Southern East Asian-dominating haplogroups, including B, F, M7, N*, and R. [141] These haplogroups account for 52.7% and 33.85% of those in the Northern Han, respectively.
The mutation emerged approximately 44,000 years ago in a lineage related to the Ust'-Ishim man in the Omsk Oblast of western Siberia. In East Asia, the derived allele appears approximately 40,000 years ago in Northern China among individuals related to the Tianyuan man. In North America, the derived allele appears approximately 12,000 years ago ...
The frequency of 370A is most highly elevated in modern North Asian and East Asian populations, followed by Native American populations, but is virtually absent in other populations around the world. [20] In a study of 222 Korean and 265 Japanese subjects, the 370A mutation was found in 86.9% Korean and 77.5% Japanese subjects. [21]
According to experts, there’s actually a gene mutation behind it. Between 80 and 95% of East Asians have a dysfunction of the ABCCII gene, which is linked to smelly pits, a number of studies say ...
The East Asian types of ADH1B in particular are associated with rice domestication and would thus have arisen after the development of rice cultivation roughly 10,000 years ago. [32] Several phenotypical traits of characteristic of East Asians are due to a single mutation of the EDAR gene, dated to c. 35,000 years ago. [33]
The inactivating ALDH2*2 mutation is "the most common single point mutation in humans". [14] This mutation is found in very few White people, but about 50% of East Asians are heterozygous for this mutation. The ALDH2*2 allele encodes lysine instead of glutamic acid at amino acid 487, [15] distorting the NAD+ binding site.
The East Asian O3-M122 Y chromosome Haplogroup is found in large quantities in other Muslims close to the Hui people like Dongxiang, Bo'an and Salar. The majority of Tibeto-Burmans, Han Chinese, and Ningxia and Liaoning Hui share paternal Y chromosomes of East Asian origin which are unrelated to Middle Easterners and Europeans.
Y-DNA haplogroup migration in East Asia. The tables below provide statistics on the human Y-chromosome DNA haplogroups most commonly found among ethnolinguistic groups and populations from East and South-East Asia. ST means Sino-Tibetan languages.
