Supplementary Figure 12: The distribution of minor two-locus genotype frequencies for all marker pairs and those showing significant epistatic effects.

The distribution of minor two-locus double homozygote genotype frequencies for (a) all pairs of markers and (b) those showing significant additive-by-additive epistatic effects, the distribution of minor two-locus single heterozygote genotype frequencies for (c) all pairs of markers and (d) those revealing significant additive-by-dominance epistatic effects, as well as the distribution of two-locus double heterozygote genotype frequencies for (e) all pairs of markers and (f) those displaying significant dominance-by-dominance epistatic effects.
