θ1, θ2, θA, m1, m2, and t are scaled by the mutation rate, whereas N1, N2, NA, 2N1m1, 2N2m2, and T are scaled by individuals or years. All estimates include the per gene mutation rate (μ), which is equal to the geometric mean of the mutation rate of all loci. θ1, N1 effective population size of the first species; θ2, N2 effective population size of the second species; θA, NA effective population size of ancestral population; HPD highest posterior density, m1 population migration rate from the second to the first species; m2 population migration rate from the first to the second species; MLE maximum-likelihood estimate, t, T time since species divergence
