There are many distinctive Jewish clusters (groups of similar
haplotypes) throughout the Y-haplogroups. In my own project for example
there are several very clear (Eastern European) Jewish clusters ...
nothing specifically Sephardic has shown up though. The reason is
probably because the Inquisitions, both in Iberia and the New World,
were very effective in breaking up Sephardic Jewish clusters ....
