Putative orthologs for Mus musculus and Mus spretus are shown in the order they appear in their respective clusters. Italics indicate likely pseudogenes. Synonymous substitution rates (dS) for orthologous pairs are typically in the 2–4% range (exceptional pairs are bolded). A range of ratios for synonymous to non-synonymous substitution rates (dS/dN) are evident; two pairs possibly subject to adaptive selection with dS/dN < 1 are bolded.
