Table 2. Effect estimates for logistic mixed model for gaps in the primary sex comb as response variable. This model had included only the HSS and LSS treatments, and these two treatments were constrained to have a common intercept, but not slope. The confidence intervals for the effect of generation in each treatment overlap.

	Estimate	Standard Error	P
Intercept	−2.30	0.25	< 2.0 x 10−16
generation-HSS	−0.034	0.021	0.106
generation-LSS	−0.026	0.020	0.188
