Table II. Expression ratios of CYC- and CIN-like genes between two parents and allele expression biases in F1 hybrids.

Data are mean ± sd of three independent biological replicates, with each including three technical replicates. The asterisk represents the ratio being significantly different (Fisher’s lsd test; H₀: Pg/Ps = 1, Pg_F1/Ps_F1 = 1, P < 0.01). DP, Dorsal petals; LP, lateral petals; VP, ventral petals.
