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.

^ Indicates a next-generation sequencing entry which does not yet meet quality guidelines for minimum number of reads.
^^ Indicates an entry which does not meet quality guidelines but may be helpful.
~ Indicates only an approximate location on the tree.

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.

NOTES:

• Identical SNPs that were discovered separately are listed in alphabetical order, not necessarily in the order of discovery, and separated by "/". Examples: M5/P73, M104/P22, M177, SRY9138
• Removed P35_1, P35_2, P35_3, not meeting quality guidelines on 11 August 2016.
• The chromosome location for M-P256 shown in Karafet (2008) seems off by one chromosome position.  All M samples from next-generation sequencing show the same mutation at adjacent chromosome position 8685231.  So this is the position tentatively listed in the ISOGG index.  Listed 31 August 2016.

Y-DNA haplogroup M reaches its known peak in Papua New Guinea, totaling one-third to two-thirds of population.  The haplogroup M Aborigines in Australia seem comparatively to be the most recent arrivals among Aborigines (Bergstrom).  

Geographic distribution so far of ancestry of modern-day haplogroup M subgroup men (not complete):
