Figure 2.

The mean of the X-chromosomal admixture fraction over time in females (red) and males (blue) from the admixed population, for a single admixture event (Equations 12 and 13). The mean X-chromosomal admixture (from source population 1) oscillates in approaching its limit (Equation 14). The limiting mean, shown in black, is the same for X chromosomes in both females and males. (A) $s_{1,0}^{\mathrm{f}}=0.25,$ $s_{1,0}^{\mathrm{m}}=\mathrm{0.5.}$ (B) $s_{1,0}^{\mathrm{f}}=0.5,$ $s_{1,0}^{\mathrm{m}}=\mathrm{0.25.}$
