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

- The Karafet et al (2008) paper made a major change to Haplogroup K. The subgroups formerly
known as K1 and K7 was moved to M2 and M3, respectively, and K2 and K5 became Haplogroups T and S, respectively.
- The 50f2/C deletion in the AZFc region of the human Y chromosome has been observed in several
different haplogroups and is not a unique event polymorphism. It is notable, however, that it
has been detected at relatively high levels in subgroups of K in Melanesia - K* (21%), and K3 (14%).
- Identical SNPs that were discovered separately are listed in alphabetical order, not necessarily in
the order of discovery, and separated by "/". Examples: M74/N12, M184/USP9Y+3178.
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.
