Y-DNA Haplogroup T and its Subclades - 2015

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 Ray Banks if the differences need clarification or if you find any broken links on this page.

The criteria for a representative SNP printed in bold for a subclade is: traditional usage, testing one in multiple labs, and/or being found in the area of the chromosome used in recent research studies.

SNPs listed below in italics (colored black or red) are quality variants from next-generation sequencing reports consistently showing as representing that subgroup.

Paragroups, subclades ending with an asterisk (*) indicate that some individuals do not test positive for any snps downstream. Since this fact is commonly known, paragroups are being omitted to simplify the display of SNPs.

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 East Africa. A famous person in Haplogroup T was Thomas Jefferson (1743-1826), the third President of the United States from 1801 to 1809.
