Selection Test of AdmixSim 2. A The variation trend of allele frequency. The grey curve represents each repeat. The red curve is the average of 500 repeats and the blue one is the theoretical value. The p-value was calculated using the Kolmogorov–Smirnov test and the average of 500 simulations was quite indistinguishable from the theoretical one. The pie chart on the right shows the statistical analysis of each repeat and the theoretical value. More than 95% of tests did not show statistical significance. B Allele fixation time under different combinations of initial frequency and selection coefficient. The fixation time reasonably decreased with the increase of selection coefficients. Moreover, the higher initial frequencies were, the fewer generations were cost to reach a fixation state
