Table 2. Partitioning phenotypic variance into environmental and genetic components using the full GKFSC model.

Backward stepwise selection was used to select the most parsimonious model for each trait. *Model non-convergence, unconstrained REML performed. Bold values are have significant LRT at p < 0.05.
