This is a worldwide project open to those who have tested Haplogroup I2* M170 + P215 + P217 - P37.2 or whose predictive Haplogroup is I2* or for those who represent such a person.

Sponsors for testing carried out by this project are welcome.

Note : For anyone reading this before they have done any testing it is recommended that as a cost benefit you should test for the highest number of markers possible (67) and only adjust downward if your budget dictates.


Predicting I2* Haplogroup
The predicted subclade with largest percent prediction will be used to place the new members haplotype in the Y-DNA Results portion of the I2* website.


Note: There is still a chance that the prediction could show an error of including I2b2 into I2* as there is no way to filter this group out, but there is a haplotype motif with 10, 12 at DYS445, 454 which almost always indicates I2b2 rather than I2*.

Over the last 6 years Haplogroup I2 and subclades I2a and I2b have been confirmed and continue to be developed. However there is still a group of results that have been classified or predicted as I2* The Timeline for this split appears to be around 14000 years ago that the I2b and I2* line split and shortly thereafter I2b2 and I2B1 parted ways. About 8000 years ago the I2* line split into the three groups A, B & C. The TMRCAs of these 3 groups are believed to be about 2000 to 5000 years ago (approx 50 to 80 generations). More recently a youngish Jewish group (J) has branched from group B which has a TMRCA of centuries (up to 30 plus generations). The actual timeline of split of groups B and J have not yet been identified.

Cost to Members

Individual. Cost of the FTDNA 67 markers and the additional SMGF markers. There amy be other test a a latter stage. See News for details.

Project. Walk the Y (WTY) testing. Members are asked to donate what they are able to towards the project to be used in test like the WTY, where intitially it is only neccessary to test one person from each group.


What are Haplogroup Projects?

Surname Projects pertain to recent ancestry, ie, four to twelve (or more) generations back. Haplogroup Projects pertain to a person's deep ancestry, ie, their ancient ethnic origins. This means thousands of years ago. So the research emphasis changes from genealogy to a mixture of Anthropology and Archaeology, but YDNA still plays a major role for the time being.

Archaeology is defined as the study of human cultures. YDNA is defined as Y-Chromosome DNA, and pertains to the male DNA which is passed from father to son(s) virtually unchanged over the eons.
