Figure 5From: 11p15 DNA-methylation analysis in monozygotic twins with discordant intrauterine development due to severe twin-to-twin transfusion syndromePearson correlation coefficients of intra-twin pair methylation differences within and between regions. Note that the majority of correlation coefficients have a positive value, indicating that intra-twin pair methylation differences within and between regions arise with consistent directionality (that is, increasing difference (= methylation recipient minus methylation donor) at one CpG going along with increasing difference at another CpG).Back to article page
