“…A large number of studies have investigated whether social mate choice is MHC-based (MHC dissimilarity, MHC diversity and specific MHC genotypes), using a plethora of study systems, techniques and approaches (Bererhi et al, 2023; Bollmer, Dunn, Freeman-gallant, & Whittingham, 2012; Gasparini, Clelia, Congiu, Leonardo, Pilastro, 2015; Geßner et al, 2017; Milinski, 2006; Potts, Wayne K. Manning, C. Jo. Wakeland, 1991; Strandh et al, 2012; Helena Westerdahl, 2004).…”

Major Histocompatibility Complex (MHC) polymorphism is maintained by balancing selection through host-pathogen interactions and mate choice. The likelihood of mate choice based on MHC-dissimilarity in songbirds has been questioned because of their rather poorly developed olfactory sense, a trait considered crucial in pre-copulatory mate choice to determine both own MHC and MHC of putative partners. However, our results suggest a mechanism where extra-pair matings can maintain high MHC polymorphism also without the need for olfactory cues. In our study population of reed warblers, Acrocephalus scirpaceus, females with extra-pair young in their broods have a higher MHC similarity with their social mate than females without extra-pair young in their broods. We suggest that when MHC similarity is high between social mates, females can improve MHC diversity in their offspring through extra-pair mating. A post-copulatory mate choice mechanism that relies on multiple copulations does not demand that females identify and actively choose MHC-dissimilar mating partners. In line with this reasoning the MHC-dissimilarity of successfully siring extra-pair males were neither different from that of social pairs without extra-pair young nor from putative extra-pair males that were breeding close to the female's social nest.

In many vertebrates, individuals choose mates due to benefits accrued via the production of offspring of high genetic quality. Genes of the major histocompatibility complex (MHC), which are associated with individual immunocompetence, provide potential benefits to choosers who mate with individuals that possess specific MHC alleles, have MHC genotypes dissimilar to their own, that are heterozygous for MHC loci, and/or are highly MHC-divergent. We review the evidence of these different modes of MHC mate choice, and the signals by which the MHC status of potential mates is assessed. MHC genes may directly or indirectly regulate individual odours, and thus enable MHC status assessment and mate choice via olfaction. For both visual and auditory signals, however, evidence of an association with MHC genes is relatively weak. Importantly, individual MHC status may be cotransmitted through multiple phenotypes, and different species may focus on different phenotypic signals due to differences in sensory sensitivity. Future research should focus on detecting phenotypic cues (including olfactory, visual, and auditory) that can signal MHC genotypes, as well as on investigating the underlying mechanisms of how MHC genes regulate these signals.
