Fig. 3From: Regional genetic differences among Japanese populations and performance of genotype imputation using whole-genome reference panel of the Tohoku Medical Megabank ProjectImputation accuracies using 1KJPN data for Japanese populations not included in the 1KJPN panel. Plot of the imputation accuracy (vertical axis, aggregate r2 value) against the non-reference allele frequency of reference panel (horizontal axis) when the 1KJPN panel was used as the haplotype reference. Each population is indicated by a different color. Each point on the curves is the average of the corresponding allele frequency binBack to article page
