Extended Data Fig. 2. Imputation accuracy of ancient DNA.

a, Imputation accuracy across 42 high-coverage ancient genomes when downsampled to lower depth of coverage values (see Supplementary Note 2 and Supplementary Table 2.1). b, Imputation accuracy for 1× depth of coverage across 9 prehistoric European genomes; c, across 5 Viking age genomes; and d, across 7 ancient genomes from Early Medieval Hungary. In all panels, imputation accuracy is shown as the squared Pearson correlation between imputed and true genotype dosages as a function of MAF of the target variant sites.
