Marine stickleback carry rare haplotypes that are found at high frequency in freshwater fish. Distributions of allele frequencies in marine fish of freshwater majority haplotypes from case 1 and case 3 loci (as defined in Figure 5) from the comparison between the combined island marine population [DaOC (Danger Island), MiOC1 (Middleton Island 1), and MiOC2 (Middleton Island 2)] and the MiFW (Middle Island freshwater) population. Allele frequency histograms are presented for 0.2 bins.
