Detection and disabled pattern of pseudogene orthologs. For each pseudogene, its orthologous sequences were retrieved and compared to the parent protein sequence. Respectively, boxes and circles represent whether a pseudogene ortholog is detected or not in a species. A cross (×) means that the hypothetical CDS is disabled. Data for non-mammalian species are not shown. The five pseudogenes shown here are (from A to E) CTA-440B3.1-001 (ENm004, PS), RP11-374F3.2-001 (ENr111, PS), RP11-98F14.4-001 (ENr132, PS), AC087380.17-001 (ENm009, NPS), and AC087380.14-001 (ENm009, NPS).
