Y-DNA Haplogroup A and its Subclades - 2014

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: 11 September 2014

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 or if you find any broken links on this page.

CLADE/SUBCLADE SYMBOLS:  Added  Redefined 
SNP SYMBOLS:  Not on 2013 tree  Confirmed within subclade  Provisional  Private  Investigation 

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.

Private SNPs are being removed from the tree and placed in the following category:
Private SNPs - After having been investigated, 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 either a single surname or to a small group of related males.

SNPs under Investigation - Additional testing is needed to confirm adequate positive samples and/or correct placement on the tree.

NOTES:

Y-DNA haplogroup A contains lineages deriving from the earliest branching in the human Y chromosome tree. The oldest branching event, separating A0-P305 and A1-V161, is thought to have occurred about 140,000 years ago. Haplogroups A0-P305, A1a-M31 and A1b1a-M14 are restricted to Africa and A1b1b-M32 is nearly restricted to Africa. The haplogroup that would be named A1b2 is composed of haplogroups B through T. The internal branching of haplogroup A1-V161 into A1a-M31, A1b1, and BT (A1b2) may have occurred about 110,000 years ago. A0-P305 is found at low frequency in Central and West Africa. A1a-M31 is observed in northwestern Africans; A1b1a-M14 is seen among click language-speaking Khoisan populations. A1b1b-M32 has a wide distribution including Khoisan speaking and East African populations, and scattered members on the Arabian Peninsula.
