Genetic effects of five epistatic QTLs for body weight in the Viriginia AIL in alternate genetic backgrounds.

Estimated additive effects with standard errors (a±SE) are given for each QTL in strata containing only individuals homozygous for HWS (HH) or LWS (LL) derived alleles at the Stratification QTL. The QTL where the HWS alleles increase the body-weight in the HH/LL strata respectively are given under the headings Additive/Transgressive (see text for more explanation).
