Pathogen-mediated selection in the immune system of rodents : Exploring selection targets, functional effects and trade-offs
Pathogens cause disease and play an important role in shaping evolution of the host immune system. They create pressure on host immunity to evolve in numerous ways, most commonly by increasing divergence between species (positive selection) or increasing polymorphisms within a population (balancing selection). Especially with balancing selection, trade-offs between different traits, for example re
