Background Paragraph: Some individuals have a specific mutation in the primary sequence of their hemoglobin molecules that causes them to aggregate, resulting in a deformation of their red blood cells. This abnormality is genetic in nature. A person may inherit the gene from one parent and have sickle cell trait (only some of the hemoglobin is hemoglobin S), which is usually not life-threatening. Inheriting the gene from both parents will result in sickle cell disease, which is a very serious condition. 
Story: Dan studied two groups of individuals. Group S that had sickle cell anemia, and group B which had normal hemoglobin. He was fascinated by the results.
Which group didn't have a specific mutation in the primary sequence of their hemoglobin molecules? Which group didn't have aggregating hemoglobin? Which group had a specific mutation in the primary sequence of their hemoglobin molecules? Which group had aggregating hemoglobin? Which group had fewer deformed blood cells? Which group had fewer members that had hemoglobin S? Which group had fewer members that may inherit the gene from one parent and have sickle cell trait? Which group had more deformed blood cells? Which group had more members that had hemoglobin S? Which group had more members that may inherit the gene from one parent and have sickle cell trait?
