Research interests
Darwin predicted that, because male and female reproductive success favors different kinds of adaptations, the forces of natural and sexual selection should operate on males and females in different and often opposite directions (this has been termed “sexually antagonistic selection”; Rice 1984). However, most quantitative traits that are influenced by sexual selection (e.g. size, growth rate, or time of maturation) are not sex-limited. Furthermore, artificial selection experiments indicate that selection on one sex for trait elaboration or reduction nearly always leads to correlated evolutionary responses in the other sex (reviewed in Rhen 2000). My research attempts to explore some of the implications of sexually antagonistic selection. Early experiments with the fruit fly are directed towards identifying the abundance and genomic locations of sexually antagonistic genes. Future work will hopefully integrate sexually antagonistic variation into traditional models of female choice.
