Effect of food treatment on variance components for a male size at maturity; b female age at maturity: additive genetic effects (V A) and maternal effects variance (V M) ± SE for a bivariate model with V A + V M + V B + V R, and V A only (+V B + V R; see Methods for details). Dark symbols represent values for fish in the control food treatment, light symbols represent values for fish in the low food treatment, and white symbols represent the covariance between the traits in the two treatments
