Principal components analysis of genetic variants of potential British Jews, the Khazar dataset, and a randomly selected subset of individuals from UK Biobank. PCA’s were calculated using the intersection of the genetic variants from the UK Biobank and the Khazar datasets. Forty principal components of the variance-standardized relationship matrix were extracted using PLINK v.1.9 [26] and the first four components were visualized: a first and second, b third and fourth principal components. The Italian and French Jews from the Khazar dataset are colored in red
