Grad position: Sex Differences in Recombination Rates

The project will focus on the evolution of sex-differences in recombination rates on autosomes using Drosophila ananassae as a model system (see my web page for background) and will involve lab work (including molecular genetics and immunostain-based cytology) and some theory:

• Quantitative PCR will be used to measure sex-differences in expression of genes known to affect recombination in females.
• This will involve primer design for candidate genes.
• Immunostaining techniques will be developed to show the centromere, synaptonemal complex and cross-over events in D. ananassae meiotic cells.
• Models for how sex differences in recombination rates can evolve will be developed.
• Predictions from several hypotheses will be tested including the hypothesis that sexual selection causes the observed sex-differences in recombination rates.

Previous experience in animal behavior, with Drosophila, and_or with molecular techniques or immunostaining would be an asset; a strong interest in evolution and behavior is required.

Position will remain open until filled.
