Table 1.
Final statistical models for the constitutive transcription intensity of immunity genes, the age at emergence and dry-weight. Strongly non-significant terms (P> 0.1) are not shown unless they are involved in higher-order interactions or control for the structure of the dataset (i.e. vial and replicate tray in the analyses of age at emergence and dry-weight). For Drosomycin expression, the main effect of the maternal line could not be calculated because of the great difference in genetic variances between larvae and adults.
