D statistics and expected coalescence time of P2 and P3 under the IUA and AS models. We assumed parameter values of tGF = 2,500, tP2 = 3,000, tP3 = 12,000, T = 25,000 (times in generations), and a constant ancestral population size equal to N = 10,000. (A) D(P1, P2, P3, O) as a function of f (IUA) and 2Nm (AS). (B) Expected internal branch length (IBL) for topologies where P2 and P3 coalesced first as a function of f (IUA) and 2Nm (AS). The rescaling for 2Nm on (A) and (B) was chosen so that 2Nm and f vary in the same range.
