understanding genetic disorders
Many mutations have no effect at all. These are called silent mutations. But the mutations we hear about most often are the ones that cause disease. Some well-known inherited genetic disorders include cystic fibrosis, sickle cell anemia, Tay-Sachs disease, phenylketonuria and color-blindness, among many others.All of these disorders are caused by the mutation of a single gene.Most inherited genetic diseases are recessive, which means that a person must inherit two copies of the mutated gene to inherit a disorder.any mutations have no effect at all.
