I'm pleased to convey news that the researcher who has been discovering the Y-SNPs in the DF series has confirmed another new SNP under I1: DF29. This SNP was identified as a candidate using 1000 Genomes Project data, which suggests that it defines a clade under I1 encompassing L22, Z58, and Z63 subclades. Z131 seems to be a brother clade to DF29. The expected position is shown schematically in the following updated provisional phylogeny based on 1000 Genomes Project sample data: http://www.box.net/shared/z8jfc4gbql7z7lnjklhh . In the process of confirming the validity of this SNP, the researcher was able to confirm the placement of DF29 upstream of Z58 and Z63. As with the earlier DF-SNPs in other haplogroups, the primer info for DF29 will be sent to Thomas Krahn of FTDNA so he can hopefully offer this for sale within a few weeks. Here are the details for DF29: Build 37 Build 36 Ancestral Derived 3626279 3686279 A G
