  • a Adults are the total of male and female F2 hybrids for indicated cross(es).

  • b χ2-value is measure of deviation from a model of independent gene action for an indicated pair of genes (discussed in materials and methods); P-values are calculated with 8 d.f. P-values <0.05 are indicated in italics.

  • c Application of the sequential Bonferroni method to the data yields a critical P-value of 0.0015 (α = 0.05); an * denotes values exceeding this significance threshold.
