Number of conserved gene loci versus number of rCNEs identified in the mouse, rat, human, and dog genomes. Graph showing the number of rCNEs found conserved in the dog, rat, mouse and human genomes versus the number of genes found conserved across the same genomes. Although almost 90% of the genes can be found in all four genomes, most rCNEs can be found only in three out of four genomes. rCNE, regionally conserved element.
