Beyond MHC: signals of elevated selection pressure on Atlantic salmon ( Salmo salar) immune‐relevant loci
Abstract Using Atlantic salmon ( Salmo salar ) as a model system, we investigated whether 18 microsatellites tightly linked to immune‐relevant genes have experienced different selection pressures than 76 loci with no obvious association with immune function. Immune‐relevant loci were identified as o...
