¹Percentage of phenotypic variance absorbed. BF1, BF2, BF3 and BF4: measures of subcutaneous fat depth taken in vivo at the age of 118.1±1.16 d; 145.9±1.53 d, 174.3±1.43 d and 196.6±8.03 d, respectively. BFt: measure of subcutaneous fat depth taken post mortem. BEL: weight of belly cut taken post mortem.

²Significant after FDR correction, not significant after Bonferroni correction.
