GA shows gene action modes, which are classified as follows: A, additive (|d/a| ≤ 0.20); PD, partial dominance (0.20 < |d/a| ≤ 0.80); D, dominance (0.80 < |d/a| ≤ 1.20); and OD, overdominance (|d/a| > 1.20). Mean phenotype traits of the P. depressa homozygote (AA), the heterozygote (AB), and the P. danxiaensis homozygote (BB) are shown. The P-value and significance of each locus segregation distortion were calculated
