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

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 investigation 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 a single surname or to a
small group of related males.
- M320 is downstream of M70. It was reported in a single Druze sample in Shen et
al (2004). Its placement relative to other SNPs under M70 is unknown. Listed 8 August 2012.
- P330 is downstream of L162. It was reported in a single Assyrian sample in Mendez
et al (2011). Its placement relative to L905 is unknown. Listed 8 August 2012.
- P327 is downstream of P322. It was reported in four closely related Palestinian
samples in Mendez et al (2011). Listed 8 August 2012.
- L1254 is downstream of L1255 and found in one branch of a Kuwaiti family.
Listed 7 October 2012.
- L447 is located downstream of L446; found in a single Armenian sample. Listed 11 January 2013.
SNPs under Investigation - Additional testing is needed to confirm adequate positive samples
and/or correct placement on the tree.
- L947 is downstream of L162. Listed 8 August 2012.
- L1364 and L1365 are at approximately P77; found in a
single WTY individual. Listed 11 January 2013.

- 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.
