Appendix 2—figure 2. Average coalescence times ${\displaystyle ⟨T_n⟩}$ for a partial sweep coalescent with effective population size ${\displaystyle N_e}$ and a Kingman coalescent with population size ${\displaystyle N_e}$.

For simplicity, a constant ${\displaystyle \beta }$ is used: Left: a high value ${\displaystyle \beta =0.25}$; Right: a low value ${\displaystyle \beta =0.05}$. For low ${\displaystyle \beta }$, the two coalescent processes are very similar until a high ${\displaystyle n}$. They considerably differ if ${\displaystyle \beta }$ is larger. Note that for the partial sweep process, ${\displaystyle T_n}$ never goes below ${\displaystyle {\rho }^{-1}}$.
