Accuracy for ADG and FCR. The effect of the weighting factor (ω) on accuracy for ADG and FCR for the four methods for two populations, where the X-axis represents ω ranging from 0.05 to 0.95, and the Y-axis indicates the correlation coefficients between corrected phenotypes (\({\text{Y}}_{c}\)) and genomic estimated breeding values (\(\hat{a}\))
