I will investigate selection on immune genes in an experimental population. By combining gene knock-down with prior knowledge about immunological pathways, I will study selection on single genes using the damselfly Coenagrion puella. Hereby, we can assess to which extent immune genes are pleiotropic in their effect on fitness. This will generate a much needed understanding about the causes and consequences of genetic variation in host immune responses.
