What is the MN blood system? What is the pattern of genetic inheritance of the MN blood system?

4 months ago

The MN blood system is a third (in addition to the ABO and the Rh) system of blood antigens also related to proteins of the red blood cell plasma membrane.

The inheritance pattern of the MN blood system is autosomal with codominance, a type of lack of dominance in which the heterozygous manifests a phenotype totally distinct from the homozygous.

The possible phenotypical forms are three blood types: type M blood, type N blood and type MN blood.
