Summary of the final general models (type III sums of squares) for myofibre characteristics, muscle weight parameters and H19 gene expression with adjusted R2 values and significance levels (P-values) of models and variables.

Only P-values for factors, interactions and nested effects retained in the final model are shown.aTotal cell CSA: Average cross-sectional area of muscle cells irrespective of cell type.bMaternal×paternal genome: Effect of maternal and paternal genome interaction.cFinal maternal weight (maternal genome): Effect of final maternal weight nested in maternal genome. ND: Not determined because of significant interaction and/or nested effect of final maternal weight.
