Amplified gene families in corals vs sea anemones. A Average number of gene copies in corals vs sea anemones. Orthogroups colored in orange have significantly more gene copies in corals compared to sea anemones and orthogroups colored in blue have significantly less gene copies in corals compared to sea anemones (binomial test, adjusted p-value < 0.001). Dot sizes correspond to the ratio of TDG for each OG in 11 coral genomes. B Heatmap of gene copy numbers in 15 species for 192 OG amplified in corals and 28 OG amplified in sea anemones. The phylogenetic tree is the output of the OrthoFinder software. C Proportion of TDG in 192 OG amplified in corals (orange), 28 amplified in sea anemones (blue), and not amplified OG (gray). The pie charts represent the proportion of TDG among the OG amplified in corals or sea anemones, in Porites lobata (orange), Pocillopora cf. effusa (red) and in sea anemones (blue)
