Exploration of selection testing results, along with the overlap between the marine positively selected genes (PSGs) and RELAX results. A Gene-wide ω values were computed during the BUSTED-PH analysis for each gene using the MG94xREV method. The x- and y-axes show the log10 transformed ω values for Test and Background branches, respectively. B Summary of the BUSTED-PH unconstrained model results (ω ≥ 1). The first facet column represents the marine PSGs (green) and the second facet column represents non-PSGs (grey). The top row shows the percentage of sites falling into each of the three ω rate classes, while the bottom row shows the distribution of ω values in each rate-class. C UpSet plot visualising intersections between the marine PSGs and each RELAX category (intensification, relaxation, insignificant). The central interaction matrix shows the combination of gene sets, with the top bar plot representing the size of the overlap. The left horizontal bar plot represents the size of the gene sets being compared
