Haplogroup Q

In human genetics, Haplogroup Q (M242) is a Y-chromosome DNA haplogroup. Haplogroup Q is a branch of haplogroup P (M45). It is believed to have arisen in Siberia approximately 15,000 to 20,000 years ago. This haplogroup contains many Siberians, Central Asians, and indigenous peoples of the Americas. Haplogroup Q Y-chromosomes are also found scattered at a low frequency throughout Eurasia. This haplogroup is diverse despite its low frequency among... more

In human genetics, Haplogroup Q (M242) is a Y-chromosome DNA haplogroup. Haplogroup Q is a branch of haplogroup P (M45). It is believed to have arisen in Siberia approximately 15,000 to 20,000 years ago. This haplogroup contains many Siberians, Central Asians, and indigenous peoples of the Americas. Haplogroup Q Y-chromosomes are also found scattered at a low frequency throughout Eurasia. This haplogroup is diverse despite its low frequency among most populations outside of Siberia or the Americas, and at least six primary subclades have been sampled and identified in modern populations. A migration from Asia into Alaska across the Bering Strait was done by haplogroup Q populations approximately 15,000 years ago. This founding population spread throughout the Americas. In the Americas, a member of the founding population underwent a mutation, producing its descendant population defined by the M3 single nucleotide polymorphism (SNP). A Biomed study observed an ancestral state Q* and a... less
