Table 4 Summary result from the generalized linear model on number of Gyrodactylus spp. Individuals per minnow host, with population group (native or introduced minnow populations) as factor and individual minnow heterozygosity as covariate. Population identity was nested under population group. In this test we only used the infected populations (29 populations, 880 individuals)
