The major histocompatibility complex is a large locus on vertebrate DNA containing a set of closely linked polymorphic genes that code for cell surface proteins essential for the adaptive immune syste

Major histocompatibility complex genes code for cell surface proteins that facilitate an organism's immune response to pathogens as well as its ability to avoid attacking its own cells. These genes ha

…from both sets of inherited alleles); (3) MHC gene variants are highly polymorphic (diversely varying from organism to organism within a species). Sexual selection has been observed in male mice choosing to mate with females with different MHCs. Also, at least for MHC I presentation, there has been evidence of…
MHC sexual selection has been observed in the black-throated blue warbler.
