  1. aData for fecundity and bacterial load was log-transformed prior to analysis in order improve the fit to normality. Values based on untransformed data are shown since estimates of the coefficient of variation on transformed data are difficult to interpret (Houle 1992).
  2. bHeritability estimates and 95% confidence intervals (in parentheses) based on variance components from restricted maximum likelihood estimators.
  3. cCVA – additive genetic coefficient of variation
  4. dCVR – residual coefficient of variation. Based on restricted maximum likelihood estimators.
