I-M26 branches with YCAII=11-11 and 21-21: Updated I-Y11222 tree

Click here to download our April 3, 2018 draft tree for I-Y11222

This tree shows the following updates:

--a new branch defined by 13843748 T to C and 17 additional SNPs. The known members of this branch have paternal ancestry from Central America and they have some marker values not typical for I-Y11222 and I-M26, including YCAII=21,21. An anonymous Puerto Rican sample from the 1000 Genomes Project is distant related to this branch. See more discussion on our previous post about Y11222  (linked below).

--there are also some I-M26 men with the very unusual YCAII=11-11, they mostly belong to the M26-"France" cluster (I-Y14720).  One of these men has completed the Big Y test, and he belongs to the more specific I-Y14722 branch, but he doesn't share additional SNPs with the two previous Big Ys for I-Y14722. Another man with YCAII=11-11 has Y14722+ results from the I2-P37 SNP Pack.

--some additional SNPs have been named and they are shown in red
