The Population Genetics of dN/dS
Black squares show the mean±two standard errors of the observed dN/dS ratio. The predicted dN/dS ratios for divergent lineages are shown in dashed lines (Equation 2); the predicted dN/dS ratios for a single population are shown in solid lines (Equation 5). Left column corresponds to results for two independent populations; right column corresponds to results for a single population. Top panels show results for θ = 0.1; bottom panels show results for θ = 0.01. The simulations for two populations were performed at L = 103 independent sites, and the simulations for a single population were performed at L = 104 independent sites.
