A. Heatmap of the minor allele frequency corrected pairwise covariance (COV) values between all individuals in the NCIG + PNG (masked) dataset (including related individuals). Individuals are listed in the same order along each axis and the population they were sampled from is indicated along the axes. Note that higher values of genotype covariance indicate greater genetic similarity. B. Heatmap of pairwise outgroup F3-statistics of the form F3(YRI;AUAx,AUAy), where AUAx and AUAy are any pair of individuals from the NCIG + PNG (masked) dataset (including related individuals). Individuals are listed in the same order along each axis and the population they were sampled from is indicated along the axes. Higher values indicate greater genetic similarity. C. Multidimensional scaling applied to the pairwise genotype covariance (COV) matrix estimated from the NCIG + PNG (masked) dataset after filtering to unrelated individuals. The first two dimensions are shown. (see Methods for further details of all three plots).
