Y STR Panel 116
Thomas Krahn
The reason why we have designed another Y-STR panel is to separate very close relationships. The FTDNA111 to YSEQ116 upgrade contains reliable single copy STR markers that still have a fast mutation rate. For example DYS711 has a very broad distribution with a repeat count of approximately 60 repeat motifs. Yet we have even more additional multi-copy STR markers available like DYF399 that are more complicated to interpret, but they allow an even higher discrimination for those who want to find differences among close cousins.
