R-Z304 is a notable subclade branching from R-Z156 and is frequently associated with early Germanic ancestral groups. It emerged during the later Bronze Age and diversified during the Iron Age, contributing to the paternal structure of populations across northern Europe.
Most common in Germany, the Netherlands and Denmark, with moderate frequencies in England and southern Scandinavia. Also identified in diaspora communities with Germanic ancestry.
R-Z304 forms several internally structured branches that help trace local expansions across the North Sea region. Its descendants are particularly useful for mapping early medieval population movements.
Z304 is widely used in European population genetics to understand the fine scale development of Germanic paternal lines.
