Logfold change in expression of genes that differ by parasite genotype (GP: F2,42 = 3.30*, F2,42 = 8.44***, F2,42 = 7.00**, F2,42 = 10.28***, F2,42 = 10.47***, F2,42 = 3.64*, F2,42 = 12.87***, F2,42 = 6.41**, F2,42 = 5.88**, F2,42 = 8.11**, F2,42 = 11.61***, F2,42 = 3.99*; *P < 0.05, **P < 0.01, ***P < 0.001) irrespective of host genotype. In each panel, the x axis lists the parasite genotypes (nos. 68, 75, and 161; bars are color-coded orange, blue, and red, respectively). Genes and their accession numbers are indicated at the top of each panel.
