- Abstract:
- Behavioural, morphological and physiological traits are shaped by natural and sexual selection. Sexual selection is a powerful force influencing both microevolutionary trajectories and macroevolutionary patterns because rapid reproductive trait divergence between the sexes and populations should be promoted. Recent studies have provided some support for these predictions, but we have no understanding of how variation in selection has changed the genetic relationships between males and females and between populations, as clearly it must. Here we will: (1) quantitatively determine changes in the genetic relationships between (a) the sexes and (b) populations selected under different sexual selection intensities to test the role sexual selection plays in determining microevolutionary paths, (2) assess how variation in sexual selection influences both mating and fertilization success to test the role sexual selection plays in generating macroevolutionary patterns, and (3) measure how different levels of sexual selection impact genetic diversity. Using experimental evolution in the fruitfly, Drosophila pseudoobscura, we have selected for four replicate populations each having three treatments -enforced monogamy, and both normal and elevated levels of promiscuity. Using these twelve populations, we will elucidate how sexual selection changes the genetic relationships between the sexes and populations and measure the genetic and evolutionary consequences of these changes. This powerful study will provide unprecedented data on how sexual selection changes the genetic structure of populations and it's role in speciation.
