Overview of the simulated scenarios. a Response to selection with either fitness (sweep, stabilizing selection) or the phenotypic value (truncating selection) being displayed for three time points. For truncating selection, the fraction of culled individuals is indicated in color. With stabilizing selection, once the trait optimum is reached, selection acts to reduce the fitness variance within a population. b Schematic representation of the trajectories of the targets of selection expected for the three different scenarios
