Table 1.

All likely models included an effect of selective treatment on flight performance. Likely models are ranked according to their Akaike information criterion (AIC_c). For each model, we provide the Akaike weight, which equals the probability that the model describes the data better than other models. All models contained an intercept and error terms associated with experimental population and isofemale line.
