Intra-population principal components analysis of 1,312 Ashkenazi Jewish (AJ) individuals with cluster 3 (C3) scores > 0.6 derived from ADMIXTURE analysis. The x-axis represents the eigenvalue (EV) for principal component 1 (PC1) and the y-axis represents the eigenvalue for principal component 2 (PC2). Different colors represent different geographical origins of AJ individuals.
