Haplogroup Q-M3
Haplogroup Q-M3 (Y-DNA) is a Y-chromosome DNA haplogroup. Haplogroup Q-M3 is a subclade of Haplogroup Q-L54.
Haplogroup Q-M3 was previously known as Haplogroup Q3. In 1996 the research group at Stanford University headed by Dr. Peter Underhill first discovered the SNP that was to become known as M3. At the time, it was called DYS191. Later studies completed the genetic bridge by determining that Q-M3 was related to Q-M242-bearing populations who traveled through Central Asia to East Asia.
==Origin and Distribution==
Haplogroup Q-M3 is one of the Y-Chromosome haplogroups linked to the indigenous peoples of the Americas. To date, such lineages also include Q-M242 branches (Q-M346, Q-L54, Q-P89.1, Q-NWT01, and Q-Z780) and haplogroup C-M130 branches (C-M217 and C-P39) which are almost exclusively found in North America. Haplogroup Q-M3 is defined by the presence of the rs3894 (M3) single-nucleotide polymorphism (SNP). Q-M3 occurred on the Q-L54 lineage roughly 10-15 thousand years ago as the migration into the Americas was underway. There is some debate as to on which side of the Bering Strait this mutation occurred, but it definitely happened in the ancestors of the indigenous peoples of the Americas.
