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.
