Sexual selection: Conflict, kindness and chicanery
Multiple mating by females can result in fitness costs for both sexes, and to reduce these costs each sex may attempt to manipulate the other. Substantial insights into the nature of this sexual antagonism have recently come from studies of two different fly species.
متن کاملThe relationship between sexual selection and sexual conflict.
Evolutionary conflicts of interest arise whenever genetically different individuals interact and their routes to fitness maximization differ. Sexual selection favors traits that increase an individual's competitiveness to acquire mates and fertilizations. Sexual conflict occurs if an individual of sex A's relative fitness would increase if it had a "tool" that could alter what an individual of ...
متن کاملMechanisms underlying sexual selection and sexual conflict in Drosophila melanogaster
The revelation that females o f many taxa mate with multiple males has broadened perspectives in sexual selection to encompass the study o f conflicts of interest between males and females over mating and reproduction. Conflict often exists between the sexes over reproductive decisions such as how often to mate, because the optimum mating rate may often be higher for males than for females. Sel...

متن کاملSexual conflict as a partitioning of selection.
Sexual conflict appears to be a powerful force in evolution. We suggest that selection theory can readily be adapted for cases of sexual conflict and illustrate how it can provide a new perspective on what traits cause conflict and might respond to its presence. Use of selection theory resolves some terminological confusion, provides operational measures of conflict and generates a conceptual t...
