The diverse evolutionary pattern of ESEs and ESSs in asymmetric pairs of paralogous exons. The values of relative difference compared to mouse orthologs are plotted for each pair of paralogous exons. For easy visualization, we plot the copy with lower element density (Low) on the abscissa axis and the other with higher density (High) on the ordinate axis. The mean genomic difference for human-mouse orthologous exons are shown by the blue lines in each plot on both axes. The black diagonal line shows the pattern of symmetric evolution. (a) ESEs; (b) ESSs.
