Results of computer simulations for mixed mutation model. The effect of mutation rate on genetic differentiation calculated from Φ
using mixed mutation model. In this model, there was a probability of 0.2 that when a mutation occurs the allele will mutate to any state. Different lines represent different migration rates. Migration rates 0.1, 0.01, 0.001, 0.0001 and 0.00001 correspond to different lines as indicated by the legend.
