Admixture time estimated under a simple model. Admixture time estimated under Scenario (I) for (a) α1 = α2 = 0.3 and t2 = 20, T = 40; and (b) α1 = α2 = 0.3 and t2 = 40, T = 60. Admixture time estimated under Scenario (II) for (c) α1 = α2 = α3 = α4 = 0.3 and t2 = 20, t3 = 40, t4 = 60, T = 80; and (d) α1 = α2 = α3 = α4 = 0.3 and t2 = 40, t3 = 80, t4 = 120, T = 140. X-coordinate is the admixture time in generations ago, with 0 being the present time. Each case was repeated 10 times, and Y = i means the ith simulation. The points in the line (Y = i) represent the admixture time estimated from the ith simulation, and the color of the points indicates the ancestral population. The dashed lines represent the simulated admixture time. For the first wave admixture, two estimations of admixture time are presented
