phil > DNA testing there’s a seperate catogory for Ashkenazim and Sephardim.
No, there is a separate category for Ashkenazim who came from a small number of medieval ancestors. The rest (loosely called Sepahardim) represent a wider DNA of all Jews from previous history, that is they consist of a much large set of groups both by DNA, and by minhagim and history. The “recent” (last 500-1000 years) growth of Ashkenazim obscures that.
