Host avoidance and resistance vary independently and are specific to parasite genotype.

Abstract excerpt

Hosts can reduce the negative fitness effects of parasite infection by avoiding contact with parasites or by resisting infection after contact. Because of their shared outcome, avoidance and resistance have been hypothesized to trade off with one another. Assuming these defences carry fitness costs, hosts are expected to have high levels of one defence or the other, but not both. Alternatively, avoidance and...
