Fig. 1. The behaviors of ${\widehat{r}}^2$ and ${\widehat{r}}_{\mathrm{\Delta }}^2$ during reproduction for the MS mating system (set N_e = 40 or 80, v = 2 or 4, L = 200 and c = 0.1).

Each of the two columns shows the results of a different ploidy level, and each of the two rows shows the results of a different effective population size. Solid gray lines denote approximate d² or δ², dotted gray lines denote exact d² or δ², and solid lines denote ${\widehat{r}}^2$ or ${\widehat{r}}_{\mathrm{\Delta }}^2$, where the lines representing δ² (or ${\widehat{r}}_{\mathrm{\Delta }}^2$) are above those representing d² (or ${\widehat{r}}^2$) for each situation.
