Pairwise comparison of orthologous and paralogous genes between (A) P. tetraurelia and P. sexaurelia and (B) P. tetraurelia and P. biaurelia. The proportion of ancestral genes that are still duplicated in both species, duplicated in one species but single-copy in the other, and single-copy in both species is shown. For genes that are now single-copy in both species, the proportion of divergent resolutions is shown on top (white) and the proportion of ancestral/parallel resolutions is shown below (gray).
