Figure 13.

Contour plots of the limit of the variance of the fraction of admixture over time as a function of $s_1^{\text{f}}$ on the x-axis and $s_2^{\text{m}}$ on the y-axis for specified values of $s_2^{\text{f}}$ by column and $s_1^{\text{m}}$ by row. The domains of $s_1^{\text{f}}$ and $s_2^{\text{m}}$ are $\left[0,1-s_2^{\text{f}}\right]$ and $\left[0,1-s_1^{\text{m}}\right]$, respectively.
