There are important variations in meiotic recombination between and within species. Despite recent studies, there is a lack of empirical data to understand how different recombination maps affect adaptation and how recombination evolve itself.
The rec-1 mutant in Caenorhabditis elegans strongly alters the normal recombination map without having direct fitness cost. We use experimental evolution methods to test how the change in recombination map may affect adaptation in a novel environment and if there is natural selection on the rec-1 mutant itself.
