Figure 5.

The variance of the fraction of admixture over time for constant, nonzero contributions from the source populations, with different levels of sex bias in the founding of the hybrid population, and constant, equal, and nonzero subsequent contributions from the source populations and sex for g ≥ 1. In all cases, $s_1^{\text{f}}=s_1^{\text{m}}=s_2^{\text{f}}=s_2^{\text{m}}=0.2$. The variance, calculated with Equation 50, reaches a nonzero limit ${\lim }_{g\to \mathrm{\infty }}\mathbb{V}\left[H_{1,g,\delta }\right]=1/24$.
