The major histocompatibility complex (MHC) plays numerous important roles in kin recognition, pathogen resistance, and mate selection. Research in fish, birds, and mammals have suggested that individuals optimize MHC diversity, and therefore offspring fitness, when choosing mates. In reptiles, however, it is unclear whether female mate choice is based on genome-wide genetic characteristics such as microsatellites DNA loci, on particular functional trait loci (e.g., MHC) or on both, and MHC effects on mate choice remain...
