Antagonistic coevolution The costs of parasitism lead to antagonistic coevolution between hosts and parasites. Hosts can evolve resistance (typically by closing the compatibility filter) or tolerance (focusing on resistance this week). Stahl et al. (1999): Arms races in a disease-resistance locus of Arabidopsis Red Queen (cyclic) new alleles arise frequently frequency-dependent selection: rare alleles in the parasite, or host, have an advantage resistance alleles tend to be monomorphic ...
