Table 1. ANOVA table for the statistical analysis of the wing pattern frequency.
Analysis of deviance table (type III Wald χ2 test) for the optimised model. The interaction between sex and food was statistically significant, with both of the two linear terms to be found non-significant. The mitochondrial genotype and the nuclear genotype had also a significant effect on the staining pattern.
