  1. A indicates additive effect; d indicates dominant effect; α indicates allele substitution effect; a single asterisk (*) means that the additive, dominance or allele substitution effect of the locus is significant (P < 0.05), and double asterisks (**) mean that the additive, dominance or allele substitution effect of the locus is extremely significant (P < 0.01)
