Huntington's disease can remain in the population due to its autosomal dominant inheritance pattern, meaning that only one copy of the mutated gene is needed for an individual to develop the disease. This allows affected individuals to reproduce before symptoms typically appear, often in mid-adulthood, enabling the gene to be passed on to future generations. Additionally, the lack of a cure and effective treatments means that the disease continues to affect families, perpetuating its presence in the population. Genetic testing and counseling can help manage risks, but the desire to have children often leads to the continued propagation of the mutation.
