Figure 4:

Variance of ancestry under a single-admixture scenario as a function of the assortative mating parameter c_11,0. (A) Autosomes, $\mathbb{V}\left[H_{1,g,\delta }^A\right]$. (B) X chromosomes in a female, $\mathbb{V}\left[H_{1,g,f}^X\right]$. (C) X chromosomes in a male, $\mathbb{V}\left[H_{1,g,m}^X\right]$. In each panel, the variance is plotted over the range of c_11,0, [−0.25, 0.25], for values of g between 1 and 6 (from darkest to lightest gray), with $s_{1,0}^f=s_{1,0}^m=0.5$, using eqs. (41), (43), and (44).
