Abstract

The current chapter examines parent-offspring conflict over mating. It is argued that, due to differences in genetic relatedness between parents and children, specific traits in a mate give different fitness benefits to each party. As a consequence, when the latter exercise mate choice, they make compromises which are not to the best fitness interest of the former. In consequence, children’s free mate choice involves an opportunity fitness cost for parents, which gives rise to parent-offspring conflict over mating. Moreover, this chapter examines the trade-offs hypothesis which has been put forward as an alternative explanation for parent-offspring conflict over mating. It is demonstrated that evolutionary trade-offs do not result in such conflict; however, they affect parent-son conflict over mating. It is further argued that the degree of parent-offspring conflict over mating is contingent upon the prevailing environmental conditions and the mate value of children.
