A possible new branch based on Big Y-700 results: 2019-07-08 tree for I-S17250

Click here to download our 2019-07-08 tree for I-S17250

This tree shows a new branch called I-FT39645, it's part of I-A2423. There are two A2423+ men who did Big Y-700, they share three SNPs called FT39645, FT42350, and FT43555. The prefix FT indicates that these SNPs were discovered in Big Y-700 results beginning in 2019 and were named by FTDNA.

But these SNPs occur in regions that weren't sequenced by the Big Y-500 test. It's possible that some of these SNPs are equivalent to A2423, and maybe all A2423+ men share some of these SNPs. Another A2423+ man has an Big Y-500 to Big Y-700 upgrade in progress, this will help us learn the correct placement of these SNPs.

This tree also shows some SNPs that are probably equivalent to Z16971, and three additional Big Y results.
