Co-inertia analysis (CoA) between neutral and adaptive data for all demographic groups. a. Principal Component Analysis (PCA) for MHC loci; b. PCA for microsatellite loci; dots represent different individuals and circles around dots with different colors represent demographic groups. c. CoA plot indicating the relative position of each demographic group on the factorial plane for the first two CoA eigenvalues. Dots and arrows represent the projected co-ordinates of each dataset (MHC and microsatellite loci, respectively), which are joined by a vector, where the length of the vector is proportional to the divergence between the datasets. d. Canonical weights for MHC alleles. e. Canonical weights for microsatellite alleles
