The allelic frequency distribution of SNPs occurring in all regions, coding and non-coding regions with A. lyrata as an outgroup sequence in all of the 939 loci: (a) all SNP; (b) gSNP sites; (c) rSNPs sites (including nfSNPs and dSNPs); (d) The number distribution of gSNPs with the fitting formula y = 1315.0 – 4535.6x + 4230.7x2 and dispersed SNPs with the fitting formula y = 1012.8-3221.7x + 2695.4x2. The expected allele frequency distribution with an outgroup sequence under a standard constant-size population genetics model in a, b and c is given by (1/i)/∑n-1j = 1 1/j, for i mutants per site, where n is the sample size (Ewens [43])
