Table 1. Number of SNPs under selection for a) each year as detected with BAYESCAN, and the individual population as detected with WFABC for b) a small (N_e = 50), and c) and a large (N_e = 500) effective population size.

For each method the number of SNPs under positive and negative selection are given along with their distribution among chromosomes (chr1–chr6) where identifiable, or otherwise listed without chromosome location (NA).
