Researchers in New York and Tel Aviv conducted a genome-wide analysis on 237 individuals from seven well-established Jewish communities around the world, hailing from Iran, Iraq, Italy, Greece, Turkey, Syria and eastern Europe.The team then compared these genetic profiles to those of non-Jews in the same geographic regions based on data from the Human Genome Diversity Project....Excerpts: "Different communities of Jews around the world share more than just religious or cultural practices -- they also have strong genetic commonalities, according to the largest genetic analysis of Jewish people to date.But the study also found strong genetic ties to non-Jewish groups, with the closest genetic neighbours on the European side being Italians, and on the Middle Eastern side the Druze, Bedouin and Palestinians.The IBD segment sharing and the proximity of European Jews to each other and to southern European populations suggested similar origins for European Jewry and refuted large-scale genetic contributions of Central and Eastern European and Slavic populations to the formation of Ashkenazi Jewry.Rapid decay of IBD in Ashkenazi Jewish genomes was consistent with a severe bottleneck followed by large expansion, such as occurred with the so-called demographic miracle of population expansion from 50,000 people at the beginning of the 15th century to 5,000,000 people at the beginning of the 19th century.

Proceedings of the National Academy of Sciences of the United States of America (PNAS) 1 (September 14, 2010): pages 16222-16227. Among the comparative populations were 1705 continental Europeans and 1251 European-Americans.

Moreover, we also show that admixture directly correlates with high LD, suggesting that admixture has increased both genetic diversity and LD in the AJ population.Family Tree DNA: Genetic Testing Service Get genetically tested to discover your relationship to other families, other Jews, and other ethnic groups. 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.Projects you might qualify to join include "Gesher Galicia - Jewish DNA Project", "Jewish Gen Belarus SIG DNA Project", "Jewish Gen Hungarian SIG DNA Project", "German Jewish Gersig DNA Project", "Jewish Frankfurt", "Sephardic Heritage DNA Project", "Jews of Rhodes Project", "The Jewish R1b Project", "Ashkenazi Levite R1a1", and "Jewish E Project". 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.Previous genetic studies of blood group and serum markers suggested that Jewish groups had Middle Eastern origin with greater genetic similarity between paired Jewish populations.However, these and successor studies of monoallelic Y chromosomal and mitochondrial genetic markers did not resolve the issues of within and between-group Jewish genetic identity.
