QTL detected for the milk traits in the AMM BC population for the following traits: protein (PP), fat (FP), lactose (LP) and useful yield (UP) content, total milk (YCUM), protein (PYCUM), fat (FYCUM), and lactose (LYCUM) yield until day 100, total somatic cell count (YSCC) and total cell score (YSCS) until day 100; shown are the QTL relative QTL position and the confidence interval (CI) along the ¹male distance map [27], the LOD score and the effect in standard deviation (SD) of the QTL; QTL effects are expressed with respect to the ancestry of Awassi grandsire contrasted with the Merino granddam
