The genes cryptography for the most molecules concerned within the human immune system--immunoglobulins, human free phagocyte matter (HLA) molecules and killer-cell immunoglobulin-like receptors (KIR)--exhibit a awfully high level of polymorphism that reveals exceptional frequency variation in human populations. 'Genetic marker' (GM) allotypes placed within the constant domains of immunoglobulin antibodies are studied for over forty years through medical science typewriting, resulting in the identification of a spread of gram haplotypes whose frequencies vary sharply from one geographic area to a different. a powerful diversity of HLA alleles, which ends in aminoalkanoic acid substitutions placed within the antigen-binding region of HLA molecules, additionally varies greatly among populations.

The KIR disagree between people consistent with each cistron content and factor variation, and additionally show hefty population diversity. Whereas the molecular evolution of those polymorphisms has possibly been subject to survival of the fittest, in the main driven by host-pathogen interactions, their patterns of genetic variation worldwide show vital signals of human geographic growth, demographic history and cultural diversification. As current developments in population genetic analysis and theoretical account improve our ability to discriminate among different--either random or deterministic--forces engaged on the genetic evolution of human populations, the study of those systems shows nice promise for work each the peopling history of contemporary humans within the time since their common origin and human adaptation to past environmental (e.g. pathogenic) changes. Therefore, additionally to mitochondrial desoxyribonucleic acid, Y-chromosome, microsatellites, single ester polymorphisms and different markers, immunogenetic polymorphisms represent essential and complementary tools for social science studies.
