The “isolation-migration” model, in which two populations diverged T generations ago from a common ancestral population. The parameters θ1, θ2, and θA are the population mutation rates per base pair for populations 1 and 2 and the ancestral population, respectively. The split time in generations is T, and m is the symmetrical migration rate between populations per generation (for details, see Methods).
