Mechanisms 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 کاملAdult fitness consequences of sexual selection in Drosophila melanogaster.
Few experiments have demonstrated a genetic correlation between the process of sexual selection and fitness benefits in offspring, either through female choice or male competition. Those that have looked at the relationship between female choice and offspring fitness have focused on juvenile fitness components, rather than fitness at later stages in the life cycle. In addition, many of these st...
متن کاملSexual selection and immune function in Drosophila melanogaster.
The evolution of immune function depends not only on variation in genes contributing directly to the immune response, but also on genetic variation in other traits indirectly affecting immunocompetence. In particular, sexual selection is predicted to trade-off with immunocompetence because the extra investment of resources needed to increase sexual competitiveness reduces investment in immune f...
متن کاملSexual selection on wing interference patterns in Drosophila melanogaster.
Animals with color vision use color information in intra- and interspecific communication, which in turn may drive the evolution of conspicuous colored body traits via natural and sexual selection. A recent study found that the transparent wings of small flies and wasps in lower-reflectance light environments display vivid and stable structural color patterns, called "wing interference patterns...
متن کاملStabilizing selection in Drosophila melanogaster.
Stabilizing selection operates on egg length in Drosophila melanogaster. The percentage of eggs hatching decreases with departure from the population mean size; this effect cannot be explained by the model of neutral variation in a quantitative character. The finding of stabilizing selection agrees with expectations for a character inherited primarily through additive effects.
