The effects of hybridization on the incubation success (hatchability) of the E. macularius, E. angramainyu, and their hybrids.

Hybridization crossing - factor group; hatchability - binomial response variable comparing hatched and failed eggs of each clutch. Coefficients (Estimate), its Standard errors (SE), Wald statistics (Wald) and significance of treatment contrasts against reference group E. macularius (P) are provided. The marginal model (geeglm function, logit link) accounts for a mother’s identity to avoid the problem of pseudoreplications. See Table 1 for explanations of the Generation and Crossing abbreviations.
