Example of an X-X orthologous group between C. elegans and S. cerevisiae. This X-X orthologous group (KOG0054: Multidrug resistance-associated protein/mitoxantrone resistance protein, ABC superfamily) has three genes in C. elegans and two genes in S. cerevisiae. The expression context conservation scores are given in the table. The gene pair with the highest score is the "most conserved X-X orthologous gene pair" (bold, yellow), the rest are the "less conserved X-X orthologs" (blue).
