In about 90% of cases, huntington’s disease is inherited. but in 10% of cases, there is no evidence that a parent has the disease. why do you think this is the case?

New mutations can also occur randomly, so there’s a chance that children of parents who didn’t inherit the gene for Huntington’s can develop a mutation in the gene that causes Huntington’s disease.
