An Updated Y-DNA Tree at ISOGG
The International Society of Genetic Genealogy (ISOGG) announced today that their Tree Team has completed the 2008 version of the Y-DNA Haplogroup Tree. This revision was a major undertaking, because, as ISOGG states in the version history, “[t]he Karafet et al paper (2008) required a significant revision to the tree and affected all haplogroups.” The reference for this paper is (Karafet T M, Mendez F L, Meilerman M B, Underhill P A, Zegura S L, Hammer M F, (2008).
New Binary Polymorphisms Reshape and Increase Resolution of the Human Y-Chromosomal Haplogroup Tree. Abstract. Genome Research, published online April 2, 2008. Supplementary Material.). From ISOGG’s official release:
MAY 04, 2008 – The 2008 version of the ISOGG Y-DNA Haplogroup Tree is now available online: http://www.isogg.org/tree/. New to the tree is a haplogroup conversion table which is downloadable in MS Word. If you do not have MS Word/MS Office, you can download openoffice.org for a compatible word processing program. Appreciation goes to Richard Kenyon and Charles Moore for their work on compiling this table.
