Search for signatures of selection in the four breed genomes as revealed by the hapFLK analysis. Values for the X-axis are chicken autosomes, and those for the Y-axis are values of statistical significance (–log10P-values). The blue line indicates threshold of significance at P < 0.01 (i.e., –log10(P) > 2), with the red line conforming to P < 0.001 (i.e., –log10(P) > 3)
