Posterior probabilities for the parameters N A , N 2 , and s. Posterior probability densities obtained by the MCMC method and by the ABC for the parameters N for ancestral effective size (NA), N Shimaa effective size (N2), and the s parameter (the proportion of NA that founded the Quechua (N1) population. Range of prior probability distributions are in Additional file 1: Table S2. N i are in number of individuals. MCMC plots: Red: three independent runs with migration rate parameters Mi = 10; Blue: three independent runs with migration rate parameters Mi = 0. ABC plots: Gray: model with no intra-locus recombination; Black: model with intra-locus recombination. Posterior probabilities for N Quechua (N 1 ), m 1 and m 2 did not yield informative densities and are presented in Additional file 1: Figure S3.
