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:
- Haplogroup T was formerly called K2 and was first called T in the Karafet et al (2008) paper.
- Identical SNPs that were discovered separately are listed in alphabetical order, not necessarily in
the order of discovery, and separated by "/". Examples M184/USP9Y+3178.
Y-DNA haplogroup T is found at low frequencies
throughout Europe and in parts of the Middle East, North Africa, and West Africa.
A famous person in Haplogroup T was Thomas Jefferson (1743-1826), the third President
of the United States from 1801 to 1809.
