Great presentation by Dr. Beider. He notes that by 1660 the Romaniote population had merged with the Sephardic & Italian populations, at least in Constantinople. My impression is that none of these populations survive in a "pristine" pre-1492 form for genetic testing.

I wonder about the origin of the Sephardic and Italian Jewish populations, how much of their ancestry was local to Spain & Southern Italy, and how much could be traced to specifically Levantine lineages (or separated from Carthage).
