  1. NOTE. Here, n=100, α = 1, and the backward/forward ratio v/μ=1 are fixed. The nominal significance level is set slightly above the relative frequency of TotD = 2 conditional on M=2. The tables show proportions of loci that tested positive via TotD| M out of those whose gene genealogies revealed recurrent mutations. θ μ (≡ 4) is the rescaled forward mutation rate. σ(≡ 4Ns) denotes the rescaled selection coefficient. Here the null distributions are based on the correct recombination rate r (per generation).
  2. a “NA” is assigned to a category with less than 10 loci with revealed recurrent mutations.
