Sickle trait is a recessive gene?

A doctor has provided 1 answer

basically yes: The mutation that causes sickle cell disease is a recessive mutation in that you need two copies of the changed gene to have the disease (or one copy plus another mutation on the other gene like beta thalassemia, hemoglobin c, hemoglobin e, etc). If you only have one copy, you have sickle cell trait.
