  • NA, number of additive (main) effects; NAA, number of epistatic effects; N, total number of effects; VA, variance of additive effects; VAA, variance of epistatic effects; VG, total genetic variance; HA, proportion of additive variance; HAA, proportion of epistatic variance; HG, proportion of total genetic variance; NA/NAA (0), proportion of epistatic effects between a pair of loci of which both lack main effects; NA/NAA (1), proportion of epistatic effects between a pair of loci of which only one has a main effect; NA/NAA (2), proportion of epistatic effects between a pair of loci of which both have main effects. HA(MAX), HA of the largest additive effect; HAA(MAX), HAA of the largest epistatic effect.
