Possible time of origin | Insufficient Data |

Ancestor | Q-MEH2 |
Defining mutations | M120 and M265 (AKA N14) |
Haplogroup Q-M120 is a subclade of Y-DNA Haplogroup Q-MEH2. Haplogroup Q-M120 is defined by the presence of the M120 Single Nucleotide Polymorphism (SNP).
Distribution
Q-M120 has descendants in modern populations across all of Eurasia and Northeastern Africa.
The Americas
Q-M120 has not been detected in pre-Colombian populations in the Americas.
Asia
Q-M120 is present in Eastern Asia. It may trace its origin to East Asia. The frequency of Q in northern China is about 4%, with many Chinese samples of haplogroup Q belonging to the subclade Q-M120.[1][2] It has been found at low frequency among Han Chinese,[1][2] Dungans,[3] Japanese,[4] Koreans,[3] and Tibetans.[5][2] Although it was reported in the Hazaras,[6] it was subsequently shown to be a lab error as demonstrated by the phylogenetic tree changes in Karafet 2008.
Europe
To date, Q-M120 has not been detected in European populations.
Associated SNP's
Q-M120 is currently defined by the M120 SNP as well as the M265 (AKA N14) SNP.
Phylogenetic Tree
This is Thomas Krahn at the Genomic Research Center's Draft tree [1] for haplogroup Q-M120.
