Abstract excerpt
Major histocompatibility complex (MHC) immune loci illustrate how natural selection shapes functional genetic diversity in wild populations. Balancing selection favors high MHC diversity within individuals and populations that persists beyond speciation, leading to shared allelic lineages among taxa. However, some vertebrates show markedly lower allelic diversity and even the loss of entire MHC gene classes....
