Final answer:
Huntington's disorder is a dominant genetic disorder caused by a mutation in the huntingtin gene. Presence of a single copy of the mutated gene is enough to cause the disorder, and individuals with the disorder have a 50% chance of passing it on to their children. The disorder has motor, cognitive, and psychiatric symptoms.
Step-by-step explanation:
Huntington's disorder, also known as Huntington's disease, is a genetic disorder caused by a mutation in the huntingtin (HTT) gene. It is an example of a dominant genetic disorder, which means that the presence of a single copy of the mutated gene is enough to cause the disorder.
Individuals with one copy of the mutated gene have a 50% chance of passing it on to their children. If a child inherits the mutated gene, they will eventually develop Huntington's disorder. The symptoms of Huntington's disorder usually appear in adulthood and include motor, cognitive, and psychiatric disturbances.
It is important to note that individuals with Huntington's disorder have a 50% chance of passing the disorder to each of their children, regardless of whether the other parent carries the mutated gene or not.
