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.

Frequently Mutating SNPs are SNPs that appear many times in many places either in one or more haplogroups. They are inconsistent and not useful for genealogical purposes.

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 I is a European haplogroup, representing nearly one-fifth of the population. It is almost non-existent outside of Europe, suggesting that it arose in Europe. Estimates of the age of haplogroup I suggest that it arose prior to the last Glacial Maximum.

The two main subgroups of haplogroup I likely divided approximately 28,000 years ago:
