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.
Distribution
The Americas
One of the 1K Genomes samples, HG01944, from Peruvians in Lima, Peru belongs to Q-M120.[1][2] Q-M120 is the other branch under Q-F746. It is best known as an East Asian branch of Q. This is intriguing; if it is not a result of post-colonial admixture, it will mark a fourth or fifth Q lineage in the Americas. The branch of Q-M120 including this sample has a calculated TMRCA of 5,000 to 7,000 years,[1] meaning that it may be the result of a later pre-Columbian immigration from North or East Asia.
Asia
Q-M120 is present in Eastern Asia and may trace its origin to
East Asia.[3][4][5] It has been found at low frequency in samples of
Han Chinese,[4][5]Dungans,[6]Hmong Daw in Laos,[7]Japanese,[8] Dörwöd
Kalmyks,[9]Koreans,[6]Mongols,[10][11]Tibetans,[5][12][13]Uygurs,[14] and
Vietnamese.[1][2] It also has been found among
Bhutanese,[15]Murut people in
Brunei,[16] and
Azerbaijanis.[1] Sengupta et al. (2006) reported finding Q-M120 in the HGDP sample of Pakistani
Hazaras,[17] 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.[18] 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.[11]
