Adult locomotory activity mediates intralocus sexual conflict in a laboratory-adapted population of Drosophila melanogaster.

ABSTRACT: The strongest form of intralocus sexual conflict occurs when two conditions are met: (i) there is a positive intersexual genetic correlation for a trait and (ii) the selection gradients on the trait in the two sexes are in opposite directions. Intralocus sexual conflict can constrain the adaptive evolution of both sexes and thereby contribute to a species' 'gender load'. Previous studies of adult lifetime fitness of the same sets of genes expressed in both males and females have established that there is substantial intralocus conflict in the LHM laboratory-adapted population of Drosophila melanogaster. Here, we investigated whether a highly dimorphic trait-adult locomotory activity-contributed substantially to the established intralocus sexual conflict. To measure the selection gradient o
