Fig 8. Effects of background selection on the accumulation of BDMi mutations (two-locus model).

The graph displays the fixation time, either without (left) or with (right) selection on the derived alleles, and under different scenarios of background selection, ‘linear BG effects’ (yellow) or ‘curved BG effects’ (red), which we compared to a scenario without background selection (blue) (see methods for details on the implementation of background selection effects in our simulations). N = 10, 000, h = 0.5, s = 2.5.10⁻⁴, h_b = k_b = 0.5, s_b = 10⁻³, r = 0.5. 10, 000 iterations.
