  1. Average imputation accuracies were split into categories of the closest recent ancestor genotyped and calculated over 10 replications; 1mean of imputation accuracy calculated as the correlation between true genotypes and imputed genotype dosages, both uncorrected for the mean gene content; 2standard deviation.
