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: Two brothers went to take a blood test. Ned had sickle cell anemia, while Ted didn't have that disease. Their mother took Ned to a specialist.
Question: Which brother didn't have misshapen cells that had difficulty passing through the smallest blood vessels?
