We have removed one outlier individual from the Mandenka population. Among the Bedouins, 24 out of 45 individuals have a higher proportion of European-related ancestry (Figure S7 in Additional file 1). If these individuals are removed from the analysis, the estimate for the admixture time in the Bedouins changes to 97 generations ago. Estimated percent European ancestry was calculated by using the two parental populations and an admixed group to find the PC1 axis. |
