Y-DNA Haplogroup Q and its Subclades - 2007
The entire work is identified by the Version Number and date given on the Main Page.   Directions for citing the document are given at the bottom of the Main Page.
Version History     Last revision date for this specific page: 17 October 2007

Because of continuing research, the structure of the Y-DNA Haplogroup Tree changes and ISOGG does its best to keep the tree updated with the latest developments in the field. The viewer may observe other versions of the tree on the Web. Email Alice Fairhurst if the differences need clarification.

NOTES:

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 Q3 sub-group is almost exclusively associated with Native American populations.
