One hundred single-locus data sets were analyzed, each with a total of 20 DNA sequences simulated using a three-parameter model with two different population sizes and unidirectional migration from population 2 to population 1 (model abbreviation is ▪). All other models 1–8 (M_i), such as the full model (□⇆▪) or the minimal model (), are compared with this “true” model (▪), which represents the M₀ hypothesis. n_param: number of parameter estimated.
