1The combined dam family “A” include the sub-families of three F1 sows: 910013, 910018 and 910097, H0 ‘no QTL effect’ versus H1 ‘same QTL effect in all dam families’.

2The combined dam family “B” include the sub-families of three F1 full-sisters: 910002, 910009 and 910010, H0 ‘no QTL effect’ versus H1 ‘same QTL effect in all dam families’.

3H0 ‘no QTL effect’ versus H1 ‘QTL effect depending on the dam family origin A or B’. Not tested for CW.

4For abbreviations of the traits, see Table 1.

5N, the number of F2 males in each combined family.

6LRT likelihood ratio test, ** 5% genome-wide significance; *** 1% genome-wide significance.

7P value of the test of the interaction effect.
