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.
