  1. 16 nested models (no migration and equal population size) were compared to the full model (significant migration and different population sizes; θAθ1θ2m1 m2).
  2. “log(P)” is the posterior probability of the model given data, “2LLR” = 2 × (Log(P)nested model-Log(P)full model), “df” is the difference in number of parameters between nested and full model, and the P-value is the probability of achieving the test statistic (2LLR) by chance under the null model. The models with P < 0.05 represent rejection of the models and they are indicated in boldface. θ1, θ2, θA are effective population sizes of population (1), population (2), and ancestral population, respectively. m1 and m2 are the gene flow from (2) to (1) and (1) to (2), respectively.
