  • There are three known samples in the I-FT240062 haplogroup, two FTDNA Big Y-700 samples and one Dante Lab sample. The two FTDNA samples are FT354262+, but the Dante Lab sample is maybe negative, or maybe this position was not tested. This SNP occurs in the centromere region
  • I-Y109702 is now the parent of I-Y99608. The three I-Y109702 samples have origin from Germany, Poland and Bohemia
  • I-A22771 is the parent of I-A22770. A DanteLab sample is A22771+ A22770-

 Click here to download our 2020-08-23 draft tree for I-Y4252


This update shows a new branch called I-ZS9184, it contains two Big Y-700 samples, one from the Netherlands and one with paternal ancestry from Hannover, Germany. These Big Ys were completed several months ago, but FTDNA added this branch very recently. ZS9184 occurs in a Y chromosome region that is sometimes considered unsuitable for phylogeny.

This update also shows a new branch called I-FT355585, it's part of the "Western-Isles" cluster (I-BY63871).

And this update shows a new branch called I-FT303575 and the more specific I-FT353020 branch.
