—Mutation rate in clustered CSEP genes versus nonclustered genes. The rate of synonymous substitution (Ks) was used as a proxy for the mutation rate in clustered CSEP genes and CSEP and non-CSEP standalone genes. For each species, groups with a distinct letter are significantly different according to a Kruskal–Wallis rank test with an FDR of 1%, adjusted for multiple testing.
