Conversion rate (percentage of genes converted) for MAPPs in the Cellular Process category of the Contributed archives. Colored lines indicate conversions per species; dashed line indicates the 50% cutoff for inclusion in the Homology MAPPs archive. As expected, highly conserved processes showed high conversion rates across species (far left), while more specialized processes were homologous only among more closely related species.
