Description

In this presentation I will discuss some of the ways that my laboratory has been trying to understand not only the developmental genetic mechanisms that regulate reproductive system development, but also how these mechanisms have evolved. I will focus on one of our recent studies which addresses the evolution of molecular mechanisms underlying reproductive capacity. We have studied different species of fruit flies, which have different reproductive capacities at least in part because of genetic differences, but which also respond differently to changes in nutrition. We have tried to determine which molecular mechanisms operate differently between these two species to give them different egg-laying capacities and also different degrees of sensitivity to starvation.
