About us

(1) To learn more about the ancient history of haplogroup II-L147 I2b and I-L596 I2a2 and define the points of separation between them and I2 and  I1 and the estimated time range for each divergence.

(2) To Increase knowledge on the HG's and further define the subgroups within them and determine if they are separate or lineal subgroups.

(3) To map those differences and time ranges with known historical events within geographical regions. The end result would be a divergence map called "The Historical Migration Routes of I2 Subgroups," with the underlying historical events.

Objective 1: Collect as much of data for each subgroup as possible to make solid inferences.

Objective 2: Define and name the known subgroups of I2b and I2a2 as lineal or divergent subclades and their geographical locations where possible.

Objective 3: Define the time of each divergence and map them.

Objective 4: Match the divergences with historical migratory events that would have preceded it.

Since WTY test was replaced by the BigY test the project has completed 50 tests. These have been very productive and it is our belief that the project should continue to use this test to find new unique SNPs and define previously named SNPs.
