Conservation score and length of exonic phastCons sequences. Using the human genome as a reference, conservation scores (A) and lengths (B) of PCSs that overlap with coding exons were determined. Compared to autosomal data (black bars), the PCSs of maternally expressed genes (red bars) are shorter and have lower conservation scores whereas PCSs of paternally expressed ones (blue bars) are similar to PCSs of autosomal genes.
