What evolutionary model for the maintenance of sexual reproduction do the following data appear to support?

Question

Quizplus · Accepted Answer

The Red Queen hypothesis suggests that sexual reproduction is maintained because it allows hosts to evolve at a rate that keeps pace with their coevolving parasites/pathogens. This is supported by the data provided, as it implies that there is constant pressure on the host population from an unpredictable environment. Muller's ratchet and the Fisher-Muller hypothesis both suggest that asexual reproduction may be more advantageous in certain scenarios, and the environmental unpredictability hypothesis does not provide a specific mechanism for the maintenance of sexual reproduction.
