BWxx is the body weight at week xx; models fitted are of the form 'Sex + QTL + Sex.QTL', except for week 98 (wethers only) for which the model was 'QTL' only; P-values were obtained from likelihood ratio tests (LRT) with 2 df (testing QTL + Sex.QTL) or 1 df (QTL only, in Week 98); these P-values were adjusted for false discovery using the method outlined in Benjamini and Hochberg [42] with *P < 0.05, **P < 0.001, ***P < 0.005, ****P < 0.0001; standardized QTL effects are expressed as the estimated effect difference (Awassi – Merino) relative to the estimated residual standard deviation
