Final answer:
A person who is a carrier of sickle cell disease produces both normal and sickle cell gametes during meiosis.
Step-by-step explanation:
A person who is a carrier of sickle cell disease produces both normal and sickle cell gametes during meiosis. As a carrier, they have one copy of the sickle cell gene and one copy of the normal gene. The carrier will produce gametes that can carry either the sickle cell allele or the normal allele.
