Effects of site (Italy vs. Sweden) and genotype (Italian vs. Swedish) were examined with GLMs with quasi-Poisson error distribution and log link function. The significance of each explanatory variable and interaction term was tested by comparing the change in deviance between the full model and a reduced model with an F-test. Significant P-values are shown in bold.
