Trait abbreviations: IMF = intramuscular fat content, WHC = water holding capacity (measured as ‘drip loss’ in percent of muscle weight), ML = Musculus longissimus, MQ = Musculus quadriceps, Glucose = blood glucose level. Phenotypes of the parental lines are compared with each other and the F1 and G3, separated for sex. Asterisks indicate significant differences between the parental lines; letters indicate significant differences between the F1 or G3 and BMMI866 (a) or BMMI806 (b) lines. Number of asterisks and letters show levels of significance (***/aaa/bbbp < 0.001, **/aa/bbp < 0.01, */a/bp < 0.05).
