Why do so many organisms have two sexual morphs: male and female?  And why do the females cross-fertilize instead of producing clonal offspring?  Assuming no concomitant reduction in fecundity, an asexual female would produce twice as many daughters (and four times as many grand-daughters) as the average sexual female; and unchecked, the resulting clone would quickly replace the sexual females and males in the population.  Our approach has been to study species that have both sexual and asexual females, so that there is a firm basis for comparison between the two reproductive strategies.  Sexual reproduction in one such species, a freshwater New Zealand snail, is correlated with the incidence of infection by parasitic trematodes, which is consistent with the idea that the production of variable, cross-fertilized progeny is favored in populations where there is a high risk of infection (The Red Queen hypothesis).  We are presently involved in more detailed genetic and ecological studies of this snail in populations where sexual and asexual females coexist.  I am also interested in the evolution of parasite virulence, and the evolution of phenotypic plasticity.  Specific details can be found at http://www.indiana.edu/~curtweb/.
