The data are divided into genome-wide and candidate loci for selective sweeps identified by Rubin and colleagues [25]. p-values are based on bootstrapping. For diversity level, pS and pN means are reported for each of the three populations broiler, layer and RJF separately. Note that the absolute values of our diversity estimates are not directly comparable to previous estimates in chicken [28] since different sequencing methodologies and sampling design were used.
