Number of selected gene clusters (#) with respective association to the four most abundant functional categories. Selected genes were identified with three different methods: PAML (green); TreeSAAP (blue); MK-Test (brown); D = “development” (GO:0009792/0002119/0009792); R = “reproduction” (GO:00000003/ 0018991); GE = “genitalia development” (GO:0048806/0040035); GR = “Growth” (GO:0040007/0040010); n = node# as referred to in the selection analyses. Note that a single cluster can belong to multiple functional categories. (Topology inferred from phylogenetic analysis (Additional file 2))
