Another example of incomplete dominance is with sickle cell anemia, a disease in which a blood protein called hemoglobin is produced incorrectly. This causes the red blood cells to have a sickle shape, making it difficult for these misshapen cells to pass through the smallest blood vessels. A person that is homozygous recessive ( ss ) for the sickle cell trait will have red blood cells that all have the incorrect hemoglobin. A person who is homozygous dominant ( SS ) will have normal red blood cells.
Context: Trisha has a doctors appointment to get some blood work done. She goes to see her doctor and he takes a blood sample. Sadly when he comes back he reports to her that her blood cells are misshapen and look like small sickles, as well as her hemoglobin is being produced incorrectly.
Question: Given a person has sickle cell anemia, is their hemoglobin produced correctly or incorrectly?
