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 north-east Eurasia.
Contents
Distribution
Q-M120 has descendants in modern populations across eastern Eurasia.
The Americas
One of the 1K Genomes samples, HG01944, from Peruvians in Lima, Peru belongs to Q-M120. 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 post colonial admixture, it will mark a fourth or fifth Q lineage in the Americas.
Asia
Q-M120 is present in Eastern Asia and may trace its origin to East Asia. It has been found at low frequency among Han Chinese, Dungans, Japanese, Koreans, Mongols, Uygurs, and Tibetans. Although it was reported in the Hazaras.
Europe
To date, Q-M120 has hardly been detected in European populations.
Associated SNPs
Haplogroup Q-M120 is defined by the presence of the M120 Single Nucleotide Polymorphism (SNP) as well as the M265 (AKA N14) SNP.
