  1. Estimates of variance components (\({\upsigma }^{2}\)), heritability (\({{\text{h}}}^{2}\)), maternal environmental effect (\({{\text{m}}}^{2}\)), and genetic coefficient of variation (GCV) of the three resilience indicators ln(variance), skewness, and autocorrelation based on average batch production for different life periods and with different intervals with standard errors (SE) for Brown
  2. NS: maternal environmental effect not significantly different from zero
  3. aTended to be significantly different from zero (i.e. 0.05 < p ≤ 0.10)
