Rapid evolution of the MH class I locus results in different allelic compositions in recently diverged populations of Atlantic salmon
We compared major histocompatibility class I allelic diversity in two currently reproductively isolated Atlantic salmon (Salmo salar) populations (Irish and Norwegian) with a common postglacial origin in order to test for among-population differences in allelic composition and patterns of recombinat...
