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.

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 - 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.
SNPs under Investigation - Additional testing is needed to confirm adequate positive samples and/or correct placement on the tree.
Y-DNA haplogroup L is found primarily as sub-group L1a (former L1) in India, Southern Pakistan and Sri Lanka. Paragroups L1b* and L1b1* (former L2*) and sub-group L1b1a (former L2a) are found at low frequencies in the Middle East and Europe. Sub-group L1c (former L3) is found mainly in northern Pakistan, northern India and west-central Asia.
