Average genetic gain (ΔG%) of growth score for among half-sib family selection (AHS) and among and within half-sib family selection (AWHS) under an additive-dominance genetic model (a mixture of additive, partial and over dominance genetic models) for three levels of heritability (0.1, 0.5, and 0.9, row-wise) and three initial parent population sizes (10, 50 and 100, column-wise). Dotted vertical lines represent the breeding cycle at which 90% of the cumulative genetic gain (ΔG90) is achieved
