2019-06-26 tree for I-S2703 (part of I-L161 "Isles")

Click here to download our 2019-06026 tree for I-S2703

We have created a new tree for the more specific I-A2330 branch (click here).
And the more specific I-Y14612 and I-S3723 branches already have their own trees.

This I-S2703 tree shows details about Big Ys and SNPs for all branches of I-S2703, except I-A2330, I-Y14612 and I-S3723

Our first tree for I-A2330 (part of I-S2742 "Isles")

I-S2703 is a large part of the I-L161 haplogroup.

According to current knowledge, everyone in I-S2703 belongs to one of two branches:
I-Y3723 which is found in Ireland and Great Britain, and which includes all of the Isles-C and Isles-D clusters.
I-S2742, which is a complex group found in Britain and Ireland, but also in Germany, Poland, Scandinavia etc.

For reasons of legibility we have created a new tree for I-A2330, it's part of I-S2742.

FT16449 seems to be an important SNP immediately below PH908: 2019-06-04 tree for I-PH908

Click here to download our 2019-06-04 tree for I-PH908

This tree shows more information about a SNP named FT16449. It's immediately below I-PH908. We included FT16449 on our previous draft tree, but with this update we show that some additional branches can be placed in I-FT16449.

Unfortunately FT16449 is inside a so-called X-transposed region which is very similar (99,5%) to a region on the X chromosome. This means that FT16449 is not suitable for individual SNP testing.

But FTDNA has already added the I-FT16449 branch to their haplotree and to their Big Y Block Tree. FTDNA has also added the I-FT14506 branch to their trees.

I-FT16449 and I-FT14506 are both part of the DYS561=16 cluster. There are several additional branches in this cluster, but no one from these branches have tested FT16449 and FT14506 because these SNPs occur in regions that weren't covered by the Big Y-500 test. See the tree for more details.
