Figure 2:

Variance of ancestry under a single-admixture scenario with assortative mating in the founding generation. (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, $\mathbb{V}\left[H_{1,g,m}^X\right]$. Each panel considers positive assortative mating (green), c_11,0 = 0.1, negative assortative mating (purple), c_11,0 = −0.1, and random mating (black), c_11,0 = 0. The plots use eqs. (41), (43), and (44) with $s_{1,0}^f=s_{1,0}^m=0.5$. For positive assortment, the variance is higher than for random mating. For negative assortative mating, the variance is lower.
