  1. We tested all combinations of three Pasteuria ramosa clones (C19, C14, C1) with 14 Daphnia magna clones. Infection trials results are defined by exposing Daphnia to the parasites and determining the infection status after 20 days. Resistant means that none of the replicates were infected. Activation was determined by observing spores in the gut of the host with a sombrero-like shape. R means that the host clone is totally resistant to the concerned parasite clone. S means that the host clone is susceptible to the concerned parasite clone. Yes means that the spores were activated.
  2. Labcross: 'Iinb1' is 'Mu11' (Belgium) selfed once; 'Xinb3' is 'X' (Finland) selfed three times; 'Xfa6' is 'AL144' selfed three times and crossed with 'Xinb3'; 'XI' is a cross between 'Iinb1' and 'Xinb3'.
