See Table I for the identity of each genotype.
Asterisks indicate genes whose expression levels exhibited significant differences among the 15 genotypes (* P < 0.05, ** P < 0.01). For each gene, comparisons of relative gene expression levels among the three genotypes from each of the nine hybrid-parent triads were carried out by one-way ANOVA, and where significant differential gene expression (P < 0.05) was identified, the detail mode of gene action is shown.
< and > indicate significantly (P < 0.05) larger or smaller, while ≈ indicates no significant difference. F, F1 hybrid; M, female parent; P, male parent; F > M≈P, overdominance; F≈M > P, positive dominance; F≈M > P, additivity; F≈P < M, negative dominance.
