Answer:

C

Explanation:

Codominant alleles mean that both alleles are expressed in the trait of the organism because no one alleles mask the effects of the other. Therefore an individual heterozygous for sickle cell will have both healthy and sickle cells in his blood. This is similar to plants with codominant alleles for petal color. If red and white color alleles are codominant, then the petals will have red and white patterns on the petals.

Answer:

c) people with two copies of the mutated gene have sickle cell anemia. people with one copy of the mutated gene have both healthy and misshapen red blood cells and are carriers of the disease
