  • 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).

  • c χ2-values exceeding P = 0.05 with 8 d.f. are indicated in italics, with the magnitude indicated by *P < 0.05 and **P < 0.01.

  • d Application of the sequential Bonferroni method to the data yields a critical P-value of 0.0008 (α = 0.05); none of the P-values in this table exceeded this significance threshold (for comparison, for the highest value, a χ2 of 21.7, P = 0.0055).
