Huntington’s disease is a dominant, lethal genetic disorder. Symptoms typically appear when a patient is in his/her 40s.  Why does the allele persist in our population? Carriers do not necessarily get sick. Carriers reproduce before they get sick. Carriers die before they can reproduce. Only male carriers reproduce before they get sick
