In a new zealand snail species, both sexual and asexual populations can be found in the same geographic region. some field observations indicated that sexually reproducing individuals are more common in the areas infested with parasites, and the reverse is also true. curt lively and mark dybdahl raised uninfected snails from many different asexual clonal lineages and then exposed them to parasites from the wild. what was their finding regarding the proportion of infected individuals, and did the results support the red queen hypothesis?

For the answer to the question above, I think that the hypothesis is supported by Lively and Dybdahl because the clonal lineages that so rare in nature had a lower proportion of infected individuals. The most common clonal lineages in nature had the highest proportion of infected individuals, it is predicted by the hypothesis.
