Fig 4. Distributions of pairwise distances for populations simulated with different parameters.

The histograms show the estimated probability mass functions ${\widehat{p}}_{\text{sim}}\left(d_{i1}\right|n_{\text{eff}},\mu )$ with selected parameter vectors (n_eff, μ). Increasing μ and/or n_eff tends to increase the distances. Each histogram represent variability in a simulated population at a single time point 6,000 generations after the beginning of the simulation.
