We investigated whether a sex-specific architecture of adult body size explains sexual conflict resolution under extreme SSD in the African hermit #spider, Nephilingis cruentata, where adult female body mass greatly (75X!!!) exceeds that of male. 1/3

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
