Distribution of $\widehat{\omega }$. Distribution of $\widehat{\omega }$under only negative selection for DFE shape parameters β=0.25,0.5,1,2. Solid curves indicate simulation results under complete linkage and dashed curves indicate results based on independently segregating sites using the PRF. Distributions were calculated from 100 sequences sampled at 6N generations with 500 replicates.
