Figure 2.

Fixation probability of allele 2 (u₂) vs. the selection coefficient s. Black is for u₂(s, β), grey is for u₂(s, 0). Solid lines are predictions according to Eq. (2) and (3), data points are for simulations with 10⁹ repeats. N = 10⁴, , β = 0.00019, T = 5 × 10⁵. Error bars are standard errors.
