I-A1328 is a major branch below I-Y4882. On our previous trees, A1328 had one equivalent SNP: Y15928. This update shows that Y15928 is below A1328 and two newly discovered SNPs are equivalent to A1328. The new SNPs are named FT16342 and FT27092.
We show FT16342 and FT27092 as equivalent to A1328 but it's possible that one or both SNPs are slightly higher in the haplotree, we couldn't check these SNPs in the I-A12505 haplogroup. But other branches like I-A10230, I-A7358 etc. are all FT16342- and FT27092-.
Most members of I-A1328 have only Big Y-500 results and in general SNPs with FT prefixes are not sampled in Big Y-500 tests. We recommend that people with Big Y results send us their VCF link and that everyone with Big Y or other NGS results order the YFull.com analysis.
**********
This update also shows a new branch called I-FT28683, it's the parent of the previously known I-BY42257/Y141127 branch. Most I-BY42257/Y141127 samples have Big Y-500 results which don't cover the FT28683 position. But one BY42257+/Y141127+ man did the the Big Y-700 test and received FT28683+ results.
We show another new branch below I-FT28683, it's called I-BY153754. It contains two samples, one with Big Y-500 results (Hungary ancestry) and a new Big Y-700 sample (Ukraine ancestry). FTDNA's Big Y Block tree currently shows four participants in I-Z16969*, one of these participants is the Hungary-ancestry man. The other three participants are not members of the I-P37 project.
Maybe FTDNA and/or YFull will update their trees and we will learn more about these SNPs and branches.
