Sephardic Project on FTDNA with a sample size of 90; which better than some papers.

It looks like Sephardic and Romaniote are ~85% similar in terms of Y-DNA. With stress on the similarity** for the reason that the uniparental clades downwards do not seem to be matching example haplogroup Q; Sephardic 100% Q1b (15%) vs Romaniote 100% Q1a (11%). Other than that, J1 and J2 seem to switch in proportionality. J1 more prevalent in Romaniote over Sephardic (just 6%). J1 dominate in Romaniote under the J clade. https://genarchivist.com/showthread.php?tid=789
Haplogroup K* being around 43% (44.4% under Romaniote). J at around 26%. Neolithic E & G at 29% (33% in Romaniote).
Interesting how did J became so prevalent in Ashkenazim with low diversity. I think it’s a bottleneck effect.
