Relationship between within-pair methylation discordance/correlation, zygosity, and chorionicity. Box-and-whisker plots of within-pair methylation discordance (Euclidean distance) and Pearson's correlation coefficient of mean-corrected values in HUVECs, CBMCs, and placenta from MZ and DZ twins, same-sex unrelated (UR) individuals, and MC and DC MZ twins. Numbers of pairs within each category are shown above each graph.
