Population bottleneck has only marginal effect on fitness evolution and its repeatability in dioecious Caenorhabditis elegans.

Abstract excerpt

The predictability of evolution is expected to depend on the relative contribution of deterministic and stochastic processes. This ratio is modulated by effective population size. Smaller effective populations harbor less genetic diversity and stochastic processes are generally expected to play a larger role, leading to less repeatable evolutionary trajectories. Empirical insight into the relationship between...
