Significance levels of random and fixed effects included in the full linear mixed effect models (model 2) investigating variation in cumulative log degree-days from fertilisation to hatch in salmon of farmed, hybrid and wild origin of C2011, C2012 and C2013.

One model was fitted per cohort. n: number of individuals included in the analysis, i.e., after mortality. Random effects: Dam; maternal identity. Strain/Fam; family nested within strain (9–10, 6–7 and 4–9 families per strain in C2011, C2012 and C2013, respectively), Family/Rep; replicate nested within family (4, 3 and 2 replicates per family in C2011, C2012 and C2013, respectively). Chi.sq; value of the Chi square statistics. Chi.Df; the degrees of freedom for the test. P; p-value of the likelihood ratio test for the random effect. Fixed effects: Strain; Mowi (C2011–C2013), Mowi × Figgjo (C2011–2013), Figgjo (C2011–2013), Figgjo × Mowi (C2012–2013), Vosso (C2012–2013), Arna (C2012–2013), SalmoBreed (C2013), SalmoBreed × Vosso (C2013), Skibotn (C2013). Log-egg; mean family log egg diameter. Strain × log-egg; interaction between strain and egg size. Sum.sq; sums of squares. Num.Df; numerator degrees of freedom. Den.Df; denominator degrees of freedom (Satterthwaite's approximation) F; F-value. P; P-value. Significant fixed effects are marked in bold. For differences in least squares means between strains of C2011, C2012 and C2013, see File S2.
