Shown are the numbers of epistatic interactions reaching significance at the 0.05 genomewise level as well as the numbers of epistatic components (aa, ad, da, and dd) that reached statistical significance (P < 0.05) for each of the traits. The chromosomes most involved in these interactions, with their number of occurrences (in parentheses), also are given. The percentage contribution of epistasis to the total phenotypic variance of each of the traits also is indicated.
