Task: Question Answering
Input (English): Background Paragraph: 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. 
Story: Doctors studied  the blood of 2 sisters, Ann and Julie. Ann had sickle cell anemia, Julie did not. 
Question: Which sister was homozygous dominant ( SS ) for the sickle cell trait?
Output (English): Julie.
