a Infection % prevalence (parasite infectivity and/or snail susceptibility) in the the co-selected intermediate hosts over line (p&s R, RU, U) and generation (p&s P1-F3) (pooled across replicates within line and within generation) (see Figure 1 for coding). b. Virulence (mean/SEM snail mortality) in the co-selected intermediate hosts over line (p&s R, RU, U) and generation (p&s P1-F3) (pooled across replicates within line and within generation) (see Figure 1 for coding).
