NOTES:

• Identical SNPs that were discovered separately are listed in alphabetical order, not necessarily in the order of discovery, and separated by "/". Example: M265/N14.

Y-DNA haplogroup Q arose in Central Asia and migrated through the Altai/Baikal region of northern Eurasia into the Americas. Today it is found in North Eurasia, with some exemplars in European populations. The Q1a3a sub-group is almost exclusively associated with Native American populations.
