Survival rates of hermaphrodites and males from the ancestral host population (EW2-30) within the selection regime. Both host sexes were tested against each of the four parasite strains used for experimental evolution in five replicates. Groups of nematodes (222 hermaphrodites or 50 males) were placed on the parasite side of Serratia selection plates (Worms Plated). Nematodes that migrated out of the parasite lawn and were alive 48 hours after exposure to the parasite were counted as survivors (Worms Alive).
