Sickle cell disease is caused by a mutation that produces an abnormal protein. The gene for sickle cell disease causes a person’s red blood cells to be shaped differently as seen in the image below. Sickle shaped red blood cells do not carry oxygen as well as normal red blood cells.
.Based on this information, which hypothesis best predicts how this genetic mutation could affect people who inherit sickle cell disease?
a. This is a harmful mutation because it decreases the cells’ ability to carry oxygen.
b. This is a beneficial mutation because the cell shape increases blood flow.
c. This is a neutral mutation because it has no effect on the individual.
This is a harmful mutation because it allows more red blood cells to carry oxygen throughout the
body.
a. This is a harmful mutation because it decreases the cells’ ability to carry oxygen.
