Am I correct if I guess the following (?):
If we inherit both maternal and paternal MHC haplotypes, the functional (non-pseudo)genes are expressed and all of their products (MHC molecules) are exhibited on the cytoplasmic membrane of any nucleated cell.
In case of MHC type I molecules our all nucleated cells bear one (or more? how many?) types of polypeptide(s) (corresponding to and) encoded by the inherited allels of each of A, B, C, E, F, G MHC-I genes.
In other words each nucleated cell expresses all MHC type I molecules encoded by our inherited MHC haplotype.
Is it true?
