The human HLA system (human leukocyte antigen) is responsible for identifying and rejecting foreign tissue in our bodies. In humans the HLA system is composed of
hundreds of multiple alleles and can have at least 30,000,000 different genotypes.
An infinite number of combinations of these genotypes is what makes the cells in
our body have a recognition code that is unique for every individual. Which
