This Y-DNA project is open to men who are either confirmed or predicted to belong to E-BY11082 (per FtDNA nomenclature) AKA subclade E-FGC32460 (per YFull nomenclature). This subclade is predominantly Ashkenazi Jewish. We also welcome men who are either confirmed or predicted to belong to upstream subclade E-BY11080 (per FtDNA nomenclature) AKA E-Z21429 (per YFull nomenclature). The upstream subclade is significantly older, thus more genetically diverse and includes non-Jewish branches.
