Influence of parasite genotype, host genotype and the maternal environment on traits describing the severity of disease at 28 days post exposure to the parasite. Shown are the treatment means for the number of offspring produced before host castration (a) and the number of parasite transmissions spores (b). Sample sizes are indicated for each treatment group. Filled square denotes M10 Daphnia clone; filled circle denotes H02 Daphnia clone; solid lines denote low-food maternal environment; dashed line denotes high-food maternal environment.
