Quantitative genetic model estimates indicated that size variation in females is to a larger extent explained by direct genetic effects than by #MaternalEffects, but in males to a larger extent by maternal than by genetic effects. These results support the hypothesis that #SexualConflict can be resolved, and #SexualSizeDimorphism maintained while allowing for current sex-specific evolution through sex-specific trait architecture. 2/3

Evolutionary biology is paying increasing attention to the mechanisms that enable phenotypic plasticity, evolvability, and extra-genetic inheritance
