Abstract

Drosophila melanogaster has been used to address many central questions in evolutionary genetics, yet relative little is known about the nature and strength of selection in this species. In this seminar I will introduce our lab based system examining selection on a number of traits, including the shape and size of the wing using various predators as agents of selection. I will describe selection acting on wing size and shape, and how both the trait, and the form of selection for shape has changed during lab based evolutionary studies.

I will then discuss our ongoing work describing the genetic architecture of wing size and shape in Drosophila, and how we aim to integrate both approaches.
