The role of major histocompatibility complex diversity in vigour of fish males (Abramis brama L.) and parasite selection

Original language description

The MHC presents a group of genes with highly polymorphic loci involved in specific immune response. The factors maintaining extensive MHC polymorphism have been questioned considering three possible hypotheses of parasite-mediated selection driving an extensive MHC diversity, i.e. heterozygote advantage, rare-allele advantage and favouring optimal MHC diversity. The patterns of MHC diversity of class IIB genes were investigated following two non-contradicting hypotheses: parasite-driven selection and MHC-based mating preferences, using males of common bream collected in the spawning period. Two allelic groups DAB1 and DAB3 were recognized from the phylogenetic analyses. Individuals expressed one or two alleles of the same or different allelic groups.Several individuals shared identical alleles, however, the presence of parasite species was not associated with the occurrence of a particular allele. The presence of different allelic groups (only DAB1, only DAB3 or both DAB1 and DAB3) i
