Haplogroup Q-M120
Human Y-chromosome DNA haplogroup
From Wikipedia, the free encyclopedia
Haplogroup Q-M120, also known as Q1a1a1, is a Y-DNA haplogroup. It is the only primary branch of haplogroup Q1a1a (F746/NWT01). The lineage is most common amongst modern populations in eastern Eurasia.
| Haplogroup Q-M120 | |
|---|---|
| Possible time of origin | 15 400 ybp |
| Possible place of origin | Asia or South Siberia[1] |
| Ancestor | Q1a1a (F746/NWT01) |
| Defining mutations | M120 and M265 (AKA N14) |
But the haplogroup might have been historically widespread in the Eurasian steppe and north Asia since it is found among Cimmerians in Moldova and Bronze Age natives of Khövsgöl.[1]
Distribution
The Americas
One of the 1K Genomes samples, HG01944, from Peruvians in Lima, Peru belongs to Q-M120.[2][3] Q-M120 is the other branch under Q-F746. It is best known as an East Asian branch of Q.
Grugni et al. (2019) found the presence of the Q-pre-M120 lineage, a precursor to Q-M120, among the Tsimshian people in Alaska.[4]
Asia
Q-M120 is present in Eastern Asia and may trace its origin to East Asia.[4][5][6] It has been found at low frequency in samples of Han Chinese,[5][6] Dungans,[7] Hmong Daw in Laos,[8] Japanese,[9] Dörwöd Kalmyks,[10] Koreans,[7] Mongols,[11][12] Tibetans,[6][13][14] Uygurs,[15] and Vietnamese.[2][3] It also has been found among Bhutanese,[16] Murut people in Brunei,[17] Tuvans,[18] Nivkhs,[19] Koryaks,[19] Yukaghirs,[19] and Azerbaijanis.[2] Sengupta et al. (2006) reported finding Q-M120 in the HGDP sample of Pakistani Hazaras,[20] but the Bayesian tree in Supplementary Figure 12 of Lippold et al. (2014) suggests that these HGDP Pakistani Hazara individuals more likely should belong to Q-L275, and that three members of the HGDP Naxi sample and one member of the HGDP Han sample should belong to Q-M120 instead.[21] Di Cristofaro et al. (2013) tested the same sample of Pakistani Hazaras and reported that they belonged to the following Y-DNA haplogroups: 1/25 C-PK2/M386(xM407, M532), 9/25 C-M401, 1/25 I-M223, 1/25 J-M530, 2/25 O-M122(xM134), 1/25 Q-M242(xM120, M25, M346, M378), 1/25 Q-M378, 1/25 R-M124, 8/25 R-M478/M73.[12]
