Sex-specific mechanistic model of admixture. At each generation g, females and males from each of two source populations, $S_1$ and $S_2,$ contribute to the admixed population, H. Contributions can vary in time. The fraction of admixture from source population $\alpha \in \left\{1,2\right\}$ for chromosomal type $\gamma \in \left\{A,X\right\}$ in an admixed individual of sex $\delta \in \left\{f,m\right\}$ is $H_{\alpha ,g,\delta }^{\gamma }.$ This model, by considering different chromosomal types, generalizes the model of Goldberg et al. (2014).
