Figure 1.
Chromosomal locations and allelic expression profiles of opossum X-linked genes in fetal brain and EEM. The x-axis shows allelic expression percentages: maternal expression on the left, and paternal expression on the right. The y-axis is the physical location of each gene along the opossum X chromosome (centromere at top). (Red bars) Maternal expression percentage; (blue bars) paternal expression percentage. The names of 24 genes that escape pXCI with >10% paternal expression (escaper genes) are indicated in the middle panel. The noncoding Rsx transcript gene (bold, red type) shows 100% expression from the paternal allele in both tissues.
