• a h2 represents the proportion of the chromosome arm additive or interaction variance component estimates to the total genetic variance.

• b ρ indicates the correlation between the product of the additive arm effects and their interaction effect with correlation coefficients significantly different from zero indicated by asterisks. If only one additive effect had a non-zero variance, the correlation coefficient shown is the correlation between the additive effect with the non-zero variance and the interaction effect.

• c *, **, and *** correspond to p-values < 0.05, 0.01, and a Bonferroni correction of 0.05/42 = 0.0012, respectively.
