Distinguishing between population bottleneck and population subdivision by a Bayesian model choice procedure.

Abstract excerpt

Although most natural populations are genetically subdivided, they are often analysed as if they were panmictic units. In particular, signals of past demographic size changes are often inferred from genetic data by assuming that the analysed sample is drawn from a population without any internal subdivision.
