From Wikipedia: In human mitochondrial genetics, Haplogroup F is a human mitochondrial DNA (mtDNA) haplogroup typical for the Far East. Haplogroup F is centered in Asia and appears throughout East Asia and Southeast Asia. It is not found in the Americas.[3] It is a descendant haplogroup of Haplogroup R. Haplogroup F. Possible time of origin 43,400 Years Before Present. Possible place of origin Asia. Ancestor R9. Descendants F1, F2, F3, F4. Defining mutations 249d, 6392, 10310. F1a clearly predominates among the representatives of haplogroup F in Southeast Asia, but subclades of this haplogroup have been found in populations as far north as the Buryats of Siberia. F1b tends to become more frequent as a fraction of total F in populations of the northern parts of East Asia and Central Asia, such as Mongols, Kazakhs, Uyghurs, and Japanese, but it is most frequent as a fraction of the total population in areas inhabited by Tai peoples, such as Thailand, Guangxi, and southern Yunnan. It is also notably frequent among the Yi people. There are odd exclaves of F1b in Gaininsk Bashkirs of Perm Oblast and Croats of Hvar Island.[20][23]
F2 has been found mainly in the form of F2a, which has been observed in more than 10% of a couple samples of Nu and Lisu from Gongshan, Yunnan.[9] F2 has been found with frequencies exceeding 5% in several other populations of Southwest China, Guangxi, and Hainan, including the Han majority population. Outside of southwestern China, F2 has been found with frequency greater than 5% in a sample of Oirat Mongols from Xinjiang and a sample of Khakas from Khakassia, with the former population boasting particularly high diversity within this clade. F3 is especially common among Austronesian peoples of Taiwan and the Malay Archipelago, but it also has been found in many populations of Southwest China and South-Central China, and in a sample of Hans from Xinjiang. Subclades:
F4 has been found mainly in aboriginal populations of Taiwan and Hainan, with some representatives among samples of Filipinos from Luzon, Indonesians from Sumatra, and Hans and Uzbeks from Xinjiang.
