Abstract:
The major histocompatibility complex class I genes comprise a bunch of classical genes (A, B, C), non-classical genes (E, F and G), pseudogenes and truncated genes. MHC-E, -F and -G are now considered immune "tolerization" molecules, which not only interact with NK cells but with T lymphocyte subsets and other cells and have a role in fetus acceptation. A strong positive directional selection is acting for maintaining the observed low polymorphism on E, F and G loci in human and apes. Invariance must be important for this non-classical class I proteins function.

Gene Duplication and Divergence
The duplicated copies of the gene are called Paralogs. Paralogs with similar sequences and functions form a gene family. Across several species, a large number of gene families are characterized.
Genetic Variation
Genes exist in different versions called alleles, which...
Lethal Alleles
Lucien Cuénot discovered lethal alleles in 1905 while studying the inheritance of coat color in mice. The agouti gene is responsible for the color of the coat in mice. This gene codes for an agouti-signaling protein, which is responsible for melanin distribution in mammals. The wild-type allele gives rise to gray-brown coat color in mice, while the mutant allele gives rise to yellow coat color. In addition to coat color, the agouti gene is associated with the yellow...
