FIG. 1.— — Plots of the expected reduction in variation due to recurrent hitchhiking based upon the theoretical prediction of Wiehe and Stephan (1993):

where θ = 4N_eμ (where N_e is the effective population size and μ is the mutation rate per site per generation), κ = 0.075 (a constant), λ = the rate of adaptive substitutions per site per generation, and γ = 2N_es (where s is the selection coefficient). By fixing μ, r, and λ, the effects of varying N_e on levels of polymorphisms are plotted for different values of s.
