INTRODUCTION: According to Columbia Encyclopedia, genetics is the “scientific study of the mechanism of heredity.” Because of genetics, we have a better understanding of such inherited diseases as Huntington’s Disease and sickle cell anemia, along with many others. Huntington’s disease, or more formally Huntington’s Chorea, is a devastating, degenerative brain disorder for which there is no effective treatment or cure. In 1993, the gene that directly causes Huntington’s disease was located and isolated. A test can be administered to determine whether or not the fatal gene is present. With the knowledge that the gene is present, there is no way to escape the disease, because everyone with that gene develops the disease. But, knowing you have the HD gene will be a determining factor in whether or not you reproduce, because your offspring would have a 50/50 chance of inheriting the gene. Sickle-cell anemia is an autosomal recessive genetic disorder characterized primarily by chronic anemia and periodic episodes of pain because the hemoglobin is defective. It is caused by a point mutation in which the amino acid valine replaces
