Living organisms are categorised into prokaryotes and eukaryotes based on their cellular features, especially the nature of membrane bound organelles and genetic material organisation. The genetic materials in prokaryotes as well as in eukaryotes are organised into chromosomes. Although the term chromosome is applicable in eukaryotes only, yet the prokaryotic genetic materials are also described

Major Histocompatibility Complex (MHC) encodes the MHC proteins present on the plasma membrane of all human tissue/cells. MHC is a tightly linked group of genes located on chromosome 6 in humans. MHC proteins are involved in intercellular recognition of foreign substance (antigen) to T-lymphocytes. Haplotypes is the term used for a group of linked MHC
