Performance of the three Forward Genomics methods on simulated data shown by precision-sensitivity plots (right) for three of the 32 trait-loss scenarios (left). Trait losses occurred at the red crosses in the phylogeny, and following trait loss the 210 trait-involved genomic regions evolved neutrally along the parts of the branches shown in red. The red cross in the precision-sensitivity plot for the perfect-match method marks its performance when we consider only genomic regions where all trait-loss species have a lower global %id value compared with all trait-preserving species. The other 29 trait loss scenarios are shown in supplementary figures 5–33, Supplementary Material online.
