The figure shown illustrates the proportion of a particular asexual snail clone in a population and the degree to which it was infected with a particular parasite. Which prediction of the Red Queen hypothesis do these results appear to reflect?

The figure shows that as the parasite load increases, the proportion of the asexual snail clone in the population oscillates. This reflects the Red Queen hypothesis prediction that there will be oscillation in the relative frequency of asexual strains in the presence of parasites. The oscillation occurs because parasites will evolve to infect the most common host genotype, which will increase the relative frequency of less common genotypes (such as sexual strains) that are less susceptible to infection.
