- Abstract:
- Selection is expected to erode additive genetic variation for traits associated with fitness; however, fitness related traits are frequently observed to have abundant genetic variation. How is this variation maintained in nature? I plan to test the prediction that negative genetic correlations between traits subject to selection in the same direction are relatively common, suggesting a major role for antagonistic pleiotropy in the maintenance of adaptive genetic variation. This idea has never been tested in a wild vertebrate population. To do this, I will use genetic paternity analysis and known maternal relationships to quantify fitness variation, and estimate quantitative genetic parameters for fitness-related traits from the reconstructed multigenerational pedigree of a natural population of bighorn sheep (Ovis canadensis) monitored over 30 years in the wild.
