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: 6 August 2012

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 or if you find any broken links on this page.

Private SNPs are being removed from the tree and placed in the following category:

Private SNPs - After having been investigated, these SNPs have not met the population distribution criteria for placement on the tree. Either too few confirmed positive testers have been found OR multiple confirmed testers were confined to either a single surname or to a small group of related males.

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.
