Nonsynonymous (A) and synonymous (B) substitution rates for DMARs in coding regions and the genes that contain those DMARs. Rates are per nonsynonymous site or synonymous site. Both DMARSS and the genes that contain them (light gray and white bars) have very low levels of amino acid divergence. (Black and dark gray bars) DMARAA have high rates of synonymous and nonsynonymous substitution, but the genes that contain them evolve at similar rates to the genomic average (dashed line).
