Table 4 Estimates with standard errors of genetic and residual variance components (\(\sigma_{a}^{2}\) and \(\sigma_{e}^{2}\), respectively), fraction of phenotypic variance explained by environmental tank effect (\(c^{2}\)), heritability (\(h^{2}\)), fraction of between-tank variance explained by genetics (\(h_{t}^{2}\)), as well as the χ2 statistics for the additive genetic family effect, with the corresponding level of significance (p)
