Y-DNA Haplogroup T and its Subclades - 2009
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: 22 September 2009

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 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.
