N₁, N₂, N_A: effective population sizes of population 1, 2 and ancestral. θ=4Nu.
m₁: the rate of gene flow from population 2 to population 1 per gene per generation. m₁=m₁/u.
m₂: the rate of gene flow from population 1 to population 2 per gene per generation. m₂=m₂/u.
2N₁m₁: the effective rate of gene flow from population 2 to population 1 per generation.
2N₂m₂: the effective rate of gene flow from population 1 to population 2 per generation.
Each value is the average of three independent runs of the simulations. Demographic quantities, N₁, N₂, N_A, m₁, m₂, and T, were converted based on a mutation rate (u) of 7.49 × 10^–9 substitutions/site/year.
