Hemoglobin exists in two forms, and alpha and a beta cluster, each on different chromosomes (11 and 16). Associated with each cluster are regions that has lost their ability to make hemoglobin due to a (frameshift) mutation. Such defunct relatives of known genes that have lost their coding ability and thus no longer expressed are known as:
A) Hemigenes.
B) Homeotic genes
C) Pseudogenes
D) Delta genes
E) Psi genes
