An immediate subclade, haplogroup D (also known as D-CTS3946), is mainly found in East Asia, parts of Central Asia, and the Andaman Islands, but also sporadically in West Africa and West Asia. The other immediate subclade, haplogroup E , is common in Africa , and to a lesser extent the Middle East and southern Europe .
Central Asian autosomal DNA geneflow was estimated as around 10%. [27] Using haplogroups that are only found in Central Asia, the study estimated Central Asian paternal and maternal contributions. Paternal contribution was estimated as between 8.5% to 15.6% based on C-RPS4Y and O3-M122 Y-chromosome haplogroups.
"East Asian Highlanders" (Tibetans) carry both Tibetan ancestry and Yellow River ancestry. Japanese people were found to have a tripartite origin; consisting of Jōmon ancestry, Amur ancestry, and Yellow River ancestry. [22] [23] East Asians carry a variation of the MFSD12 gene, which is responsible for lighter skin colour. [24]
Human-mediated gene flow: The captive genetic management of threatened species is the only way in which humans attempt to induce gene flow in ex situ situation. One example is the giant panda which is part of an international breeding program in which genetic materials are shared between zoological organizations in order to increase genetic ...
Listed here are notable ethnic groups and populations from West Asia, Egypt and South Caucasus by human Y-chromosome DNA haplogroups based on relevant studies. The samples are taken from individuals identified with the ethnic and linguistic designations in the first two columns, the third column gives the sample size studied, and the other columns give the percentage of the particular haplogroup.
Haplogroup C is found in ancient populations on every continent except Africa and is the predominant Y-DNA haplogroup among males belonging to many peoples indigenous to East Asia, Central Asia, Siberia, North America and Australia as well as a some populations in Europe, the Levant, and later Japan.
The finding that "Mitochondrial Eve" was relatively recent and African seemed to give the upper hand to the proponents of the Out of Africa hypothesis.But in 2002, Alan Templeton published a genetic analysis involving other loci in the genome as well, and this showed that some variants that are present in modern populations existed already in Asia hundreds of thousands of years ago.

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.
