Application of the DPCoA-MCoA to the simulateddata set. The parameter m is the migration rate of the simulated linear stepping stone. The DPCoA-MCoA was applied on the simulated data set, A) with allele frequency and distance information, B) with allele distances without allele frequencies, C) with allele frequencies without allele distances. Each figure A) B) and C) comprises two series of four subfigures. In the first row, for each locus the compromise pattern of differences among populations (Numbers in boxes) is given with lines relating the compromise to the ten first loci submitted to the stepping stone model. In the second row, for each locus the compromise pattern of population differences is also given at the beginning of the arrows, and this time, the arrows point at the position of each population according to the atypical locus. The longer the arrow, the more different the pattern inferred by the atypical locus from the compromise pattern. Eigenvalue barplots are provided for analyses A), B), and C).
