Y-DNA Haplogroup K and its Subclades - 2008
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: 23 December 2008

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 K is an old lineage established approximately 40,000 thousand years ago whose origins were probably in southwestern Asia. At present this group contains two distinct classes of subgroups: (1) major groups L to T (refer to the main tree at Y-DNA Haplogroup Tree) and (2) minor groups K* and K1 to K4 which do not have any of the SNPs defining the major groups. These groups are found at low frequencies in various parts of Africa, Eurasia, Australia and the South Pacific.
