The joint distributions of ΛMAX and ωMAX in scenarios with and without selection. (A) We compare the joint distribution of ΛMAX and ωMAX between a model with selection (α = 500) in a constant population and a standard neutral model. The overlap between the distributions is limited and the scenarios can be discriminated by the SweepFinder (y-axis) and to a lesser extent by the ω-statistic (x-axis). (B) We compare a model with selection (α = 500) with a neutral model that has experienced a bottleneck as it has been inferred by Li and Stephan (2006). Neither of the statistics can discriminate accurately the two scenarios (see also Table 2). Note that the scales of the statistics are different in A and B.
