Plots of the PPP-values estimated with model 2 against the BF (in dB) computed with model 3.

A) Results for the PDM data set with T = 100 generations and J = 8 populations simulated under a pure-drift demographic model. B) Results for the MDM data set with FST = 0.1 and J = 8 populations simulated under a migration-drift demographic model. In A) and B) neutral (simulated) SNPs are plotted in grey while SNPs subjected to positive (respectively balancing) selection are plotted in red (respectively blue). Depending on their underlying simulated coefficient of selection, plots latter are represented by a triangle (s = 0.02), a circle (s = 0.05) or a square (s = 0.10). C) Results from the analysis of the data set consisting in 36,320 SNPs genotyped on 9 West-African cattle populations [12]. SNP localized within the first (last) half of the SNP specific FST distribution, as previously estimated [12], are plotted in blue (red), the color being darker for those within the first (last) quarter of this same distribution.
