|Possible time of origin||10 to 15 thousand years ago|
|Possible place of origin||Beringia: Either East Asia or North America|

|Defining mutations||M3 (rs3894)|
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.
Populations carrying Q-M3 are widespread throughout the Americas. Since the discovery of Q-M3 several subclades of Q-M3 bearing populations have been discovered in the Americas as well. An example is in South America where some populations have a high prevalence of SNP M19 which defines subclade Q-M19. M19 has been detected in 59% of Amazonian Ticuna men and in 10% of Wayuu men. Subclades Q-M19 and Q-M199 appear to be unique to South American populations and suggests that population isolation and perhaps even the establishment of tribes began soon after migration into the Americas.
The Q-M3 lineage has not been detected in the European population.
Q-M194 It has only been found in South American populations.
Q-M199 This lineage has only been found in South American populations.
Q-L663 This lineage was discovered by citizen scientists. It may be linked to indigenous populations in the Southwestern United States and Mexico.
Q-L766 This lineage was discovered by citizen scientists. It may be linked to indigenous populations in the Southwestern United States and Mexico.
Q-L883 This lineage was discovered by citizen scientists.
Q-L888 This lineage was discovered by citizen scientists.
Q-M3 is defined by the SNPs M3 and L341.2.
