  • a These QTL are not replicated after correcting phenotypes for body weight variation (see Table S6).

  • b QTL for these phenotypes on these linkage groups were identified previously by Gleason et al. (2016).

  • c These QTL replicate after correcting phenotypes for body weight variation (see Table S6).

  • d Calculated via the R/qtl fitqtl function.

  • e Calculated via the R/qtl fitqtl function. Describes the phenotypic effect of substituting a FL-derived allele for a KS-derived allele.

  • f The statistical power to detect a QTL of the stated effect using our experimental design (see “Materials and Methods”).
