Fig. 5From: X Chromosome Inactivation Patterns Correlate with Fetal-Placental Anatomy in Monozygotic Twin Pairs: Implications for Immune Relatedness and Concordance for Autoimmunity Comparison of the SD values for X inactivation patterns in various groups of twins The distribution of SD values for all 41 twin pairs is shown at the left. The monochorionic, dichorionic, concordant (C), and discordant (D) twins are also plotted separately.Back to article page
