متن کاملRapid evolution of the intersexual genetic correlation for fitness in Drosophila melanogaster
Sexual antagonism (SA) arises when male and female phenotypes are under opposing selection, yet genetically correlated. Until resolved, antagonism limits evolution toward optimal sex-specific phenotypes. Despite its importance for sex-specific adaptation and existing theory, the dynamics of SA resolution are not well understood empirically. Here, we present data from Drosophila melanogaster, co...
متن کاملThe Intersexual Genetic Correlation for Lifetime Fitness in the Wild and Its Implications for Sexual Selection
BACKGROUND The genetic benefits of mate choice are limited by the degree to which male and female fitness are genetically correlated. If the intersexual correlation for fitness is small or negative, choosing a highly fit mate does not necessarily result in high fitness offspring. METHODOLOGY/PRINCIPAL FINDING Using an animal-model approach on data from a pedigreed population of over 7,000 col...
متن کاملReverse evolution of fitness in Drosophila melanogaster
The evolution of fitness is central to evolutionary theory, yet few experimental systems allow us to track its evolution in genetically and environmentally relevant contexts. Reverse evolution experiments allow the study of the evolutionary return to ancestral phenotypic states, including fitness. This in turn permits well-defined tests for the dependence of adaptation on evolutionary history a...
متن کاملRapid independent trait evolution despite a strong pleiotropic genetic correlation.
Genetic correlations are the most commonly studied of all potential constraints on adaptive evolution. We present a comprehensive test of constraints caused by genetic correlation, comparing empirical results to predictions from theory. The additive genetic correlation between the filament and the corolla tube in wild radish flowers is very high in magnitude, is estimated with good precision (0...
