Results of a binomial logistic regression; DE denotes the German origin of the stickleback (SB) or the parasite, NO the Norwegian origin, DE-mat-Hyb the hybrid origin of the stickleback with German mother while NO-mat-Hyb refers to the hybrid families with Norwegian mother. Table shows the pairwise comparisons for fish origin of the models described in Table 2, significant P-values (<0.05) in bold
