  • Adiposity QTLs are taken from Cheverud et al. (22). Chromosomal location and markers chosen to test for replication and interactions are indicated. All QTLs with the exception of Adip1 and Adip4 replicated for at least one of the associated markers tested. All loci replicated in the sample were fed a low-fat diet with the exception of Adip7, which only replicated in female animals fed a high-fat diet. Traits that are significantly affected by diet-by-genotype interactions for each locus are shown in the right-hand column. Sex-specific effects are indicated by (f) for female-specific effects or (m) for male-specific effects.
