This update shows a new branch immediately below I-Z17855. This branch is characterized by a single SNP: ChrY position 3272203 C to T. This SNP unites two existing branches: I-BY116090 and I-Y68571.
The I-BY116090 branch contains a Dante Lab sample from Serbia, and a FTDNA Big Y-500 sample with ancestry from Istanbul, Turkey. At ChrY position 3272203, the Serbian man has a positive T+ result, but this position wasn't sampled in the Turkish man's Big Y-500 test.
The I-Y68571 branch contains three samples, I think they all have ancestry from Russia. The newest sample has Big Y-700 results and a positive T+ result at position 3272203. The other two men did earlier Big Y-500 tests which didn't sample this position.
YFull already shows the I-BY116090 branch, and the Russian with Big Y-700 results has ordered the YFull analysis of his BAM file. Probably YFull will add the upstream branch at position 3272203 at the next update. FTDNA doesn't include the I-BY116090 branch and won't add the upstream branch because FTDNA doesn't include data from Dante Lab samples.
