Genetic studies on Jews In 2012, two major genetic studies were carried out under the leadership of Harry Ostrer, from the Albert Einstein College of Medicine. The results were published in the Proceedings for the National Academy of Sciences. The genes of 509 Jewish donors from 15 different backgrounds and 114 non-Jewish donors of North African origin were analyzed. Ashkenazi, Sephardi, and Mizrahi Jews were found to be closer genetically to each other than to their long-term host populations, and all of them were found to have Middle Eastern ancestry, together with varying amounts of admixture in their local populations. Mizrahi and Ashkenazi Jews
Ashkenazi Jews in Israel class, and the disparity between Ashkenazim and Mizrahim diminished (but did not completely disappear), with Mizrahi political expression becoming increasingly linked to the Likud and Shas parties; Shas was founded as a party to represent Mizrahim while Likud, the largest right-wing party, in Israel became increasingly influenced by Mizrahi political articulation, with the Mizrahi middle class' political coming-of-age held by political science commentators to be embodied by the rise of Mizrahi Likud politicians such as Moshe Kahlon and Miri Regev. The Ashkenazi vote has, aside from electorally limited majority-Ashkenazi ultra-religious parties such as Habayit Hayehudi, long been associated with secularism
