  • For all divergence scenarios considered in Figures 2 and 3 the outcome of the two neutrality tests in our simulations is summarized. Both tests are accurate under neutrality but in all cases of selection, one of them fails. However, at least one test is accurate so that the joint use of tests i and ii allows detecting all selection regimes.

  • a An outcome that does not correspond to the correct situation (in all cases it corresponds to a high type II error risk).
