Abstract: "The Ashkenazi Jewish (AJ) population has long been viewed as a genetic isolate, yet it is still unclear how population bottlenecks, admixture, or positive selection contribute to its genetic structure.

Here we analyzed a large AJ cohort and found higher linkage disequilibrium (LD) and identity-by-descent relative to Europeans, as expected for an isolate.
[...] Consistent with recent reports (13, 20, 23-25), principal component analysis (PCA) using these combined datasets confirmed that the AJ individuals cluster distinctly from Europeans, aligning closest to Southern European populations along the first principal component, suggesting a more southern origin, and aligning with Central Europeans along the second, consistent with migration to this region (Fig.
S1)." Excerpts from page 16223: "The higher diversity in the AJ population was paralleled by a lower inbreeding coefficient, F, indicating the AJ population is more outbred than Europeans, not inbred, as has long been assumed (P "Through genomic analysis, researchers at Emory University School of Medicine have shown that the Ashkenazi Jewish population is genetically more diverse than people of European descent, despite previous assumptions that Ashkenazi Jews have been an isolated population.
Order a DNA kit from FTDNA's headquarters in the USA This page collects Y-DNA and mt DNA data and analysis related to traditionally Rabbinical Jewish populations of the world, including: Ashkenazim (Jews of Northern and Eastern Europe) • Sephardim (Spanish and Portuguese Jews) • Mizrakhim (Middle Eastern Jews) • Italkim (Italian Jews) • Caucasian Mountain Jews (Dagestani and Azerbaijani Jews) • Georgian Jews • Indian Jews • North African Jews • Yemenite Jews • Ethiopian Jews Steven M. However, paradoxically we also found higher genetic diversity, a sign of an older or more admixed population but not of a long-term isolate.
Also used for comparison were 3 Middle Eastern populations: Palestinian Arabs, Druze, and Bedouins.

Abstract: "For more than a century, Jews and non-Jews alike have tried to define the relatedness of contemporary Jewish people.
Since that time, Jewish communities have migrated from the Middle East into Europe, North Africa and across the world. This study shows that although Jewish people experienced genetic mixing with surrounding populations, they retained a genetic coherence along with a religious one.Thus, the AJ population shows evidence of past founding events; however, admixture and selection have also strongly influenced its current genetic makeup." Excerpts from page 16222: "The Ashkenazi Jewish (AJ) population has long been viewed as a genetic isolate, kept separate from its European neighbors by religious and cultural practices of endogamy (1).
