Final least squares model of sperm competition success (P₂) of inbred males (first-order autoregressive variance covariance structure [AR1] and “treatment” as a variance covariate)

Effect	Parameter estimate	SE of the estimate	t	P
Intercept (arc sin sqrt transformed)	1.50	0.015	98	<0.000
Highly inbred lines	−0.068	0.029	−2.38	0.018
Moderately inbred lines	−0.005	0.022	−0.21	0.83

Intercept equals outbred control lines; df (residual) = 423.
