  1. Estimates of genetic correlations with standard errors (in parentheses) between the resilience indicators ln(variance), skewness, and autocorrelation based on average batch production for the same life periods, but with different intervals for White (below the diagonal) and Brown (above the diagonal, italic)
  2. aAnalysis did not converge
  3. bNot tested, because one or both traits were not heritable (i.e. not significantly different from zero)
