New phylogenetic tree of Haplogroup I2

Thanks, Sparkey No worries, it does make us feel special

Per Nordtvedt, Geno 2.0 has produced a "horde" of new SNPs relevant to I2c: PF3911, PF3917, PF3931, PF3938, PF3927, PF3887, PF3889, PF3893, PF3895, PF3896, PF3898, PF3903, PF3906, and F2554. All of these were found in a Hungarian I2c-B sample but not in L460+ samples, and they could all be anywhere on the tree from the split with L460+ to private. That is, expect some to unite I2c with I2b-ADR, some to be equivalent to L596, some to uniquely define I2c-B, and some to subdivide I2c-B.

would you know the subclades which belong to

I2a3 - alpine

I2a3 - western

They are united with the SNP L1286, and have just been united with M26 with the Geno 2.0 SNP CTS595. Alpine is L1286+ L233- L348-; Western is L1286+ L233+ L348-; and there is an outlier group (surname Fleming) that is L1286+ L233+ L348+.

The latest I2c Geno 2.0 sample comes from the L1251+ ("C") branch, and several of the SNPs mentioned earlier as being in the A branch but not the B branch, such as PF3881, were found in the L1251+ sample. So, that unites clusters A and C. We need more samples, but PF6328 could uniquely define the A branch, because that one was not on the C branch.

So now we have SNP definitions for the 3 I2c branches:
"A": PF3881+ L1251-
"B": PF3881- L1251-
"C": PF3881+ L1251+

Group B is the outlier, which makes sense considering how much its geographic distribution differs.
