- Female mate choice is one mechanism of sexual selection and, provided there is adequate genetic variation in the male traits that are the target of this selection, they will evolve via female choice. Cuticular hydrocarbons (CHCs) are important in Drosophila mate choice, but relatively little is known about the underlying genetic architecture of CHC profiles in Drosophila simulans. Here we used gas chromatography-mass spectrometry to investigate patterns of genetic variation in the CHC profiles of male and female D. simulans using iso-female lines. We found substantial genetic variation for CHC profiles and individual CHC components, and individual CHCs were frequently strongly genetically correlated, with a tendency for negative covariance between long and short chain CHCs in males. Intersexual genetic covariances were often weak and frequently differed in sign. These findings are novel and significant, highlighting the previously unexplored genetic architecture of CHCs in D. simulans and suggest that this architecture may facilitate sex-specific CHC evolution.
- JOH-2011-107.R2-Dryad_UploadThis is a Microsoft Excel (c) spreadsheet containing the raw data for JoH ID JOH-2011-107.R2. Column headings are self explanatory and have comments attached to the header cells. Data contained in columns I to AA represents area for CHC peaks 1-19 as quantified from chromatograms and data in columns AC to AU is the area expressed in proportional values after dividing by the pentadecane standard (peak 1).
