(A) Overall proportion of all annotated ancestries across the training set (left) and testing set (right). Numbers over each bar indicate total within each category. EUR, European; ADM, Admixed; EAS, East Asian; AFR, African; SAS, South Asian; NAM, Native American (B) High-confidence proportion (left) and accuracy (right) for European (EUR), East Asian (EAS), African (AFR) and South Asian (SAS) compared to the overall high-confidence proportion and accuracy across the test set. P-values from a two-sided Fisher's exact test comparing the proportions of these metrics to the overall distribution per ancestry are shown above each bar.
