Heatmap showing the negative logarithms of Bonferroni-correctedpvalues of hypergeometric tests, comparing the number of shared genes across pairs of phenotypic traits with joint signatures of intensified or relaxed selection. Using Pearson correlation coefficients as distance metric (shades of blue; the log10pvalue legend was capped at 25) and average linkage between pairwise comparisons as clustering criterion, the (identical) left and right dendrograms show the hierarchical clustering of co-evolving traits, primarily as triangles adjacent to the baseline, in orange for intensified selection and in purple for relaxed selection.
