Hereditary hemochromatosis (HH) is a genetic condition that causes "iron overload." Patients with severe forms of the disease must donate blood regularly to remove excess iron from their bloodstreams. Clinically, it is difficult to determine which HH patients will actually develop increased iron levels and the adverse symptoms associated with the disorder. Which type of inheritance pattern describes the inability to predict whether an individual with the HH allele will develop the disorder based on their genotype?
