a Infection % prevalence (parasite infectivity) in the Novel (i.e. not co-selected) intermediate hosts over line (p R, RU, U through s N) and generation (p F1-F3) (pooled across replicates within line and within generation) (see Figure 1 for coding). b Virulence (mean/SEM snail mortality) in the Novel (i.e. not co-selected) intermediate hosts over line (p R, RU, U through s N) and generation (p F1-F3) (pooled across replicates within line and within generation) (see Figure 1 for coding).
