Figure 2

Estimated proportions of ancestry from the continuous gene flow (CGF) model (see main text). See Table 2 for default parameters. (A) Results for varying divergence time while keeping the migration rate constant at 4 Nm = 50. (B) The estimated ancestry proportions for keeping the divergence time constant at T = 10 while varying the migration rate. Error bars denote the standard deviation of the estimated ancestry proportion per population. Simulations were produced using the following ms command [75]: ms 200 5000 -t 2 -I 2 100 100 -em 1 2 2000 -n 2 1 -ej 2 1.
