Genetic studies on Jews related they were through IBD. Individuals within the Ashkenazi, Sephardi, and Mizrahi groups shared high levels of IDB, roughly equivalent to that of fourth or fifth cousins. All three groups shared many genetic features, suggesting a common origin dating back more than 2,000 years. The study did find that all three Jewish groups did show various signs of admixture with non Jews, with the genetic profiles of Ashkenazi Jews indicating between 30% and 60% admixture with Europeans, although they clustered more closely with Sephardi and Mizrahi Jews. In July 2010, Bray et al., using SNP microarray techniques and linkage analysis,
