Sample clustering in terms of imprinting-inclined SNPs. Spearman correlations were calculated between each pair of samples using the posterior on each SNP calculated by dsPIG in each sample. Hierarchical clustering was conducted with average linkage as the agglomerative method. Posterior probabilities of African American samples were computed with African American allele frequency in panel (a) and with Caucasian allele frequency in panel (b).
