  • SD, standard deviation. Θ = 4Neμ, where Ne is the effective population size and μ is the mutation rate. γ 4Nem, where m is the migration rate. In two cases the numbers of replicates N are 81 and 92, respectively, instead of 100: the program failed to find the maximum of the likelihood surface and these cases were excluded. The values shown are for population 1; those for population 2 are similar.
