Sickle-cell anemia is an example of codominance. what implications does this have for people with one or two copies of the sickle-cell gene?

a. people with two copies of the mutated gene have healthy red blood cells. people with one copy of the mutated gene don't have the disease but are carriers of the disease.
b. 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.
c. people with two copies of the mutated gene are carriers of the disease. people with one copy of the mutated gene don't have the disease.
d. people with two copies of the mutated gene have sickle-cell anemia. people with one copy of the mutated gene have healthy red blood cells.

Humans are believed to have evolved in coastal regions in east africa. the region had an abundant supply of fish for early humanoids to eat. when scientists analyze the fads gene they see an interesting pattern. people whose families have lived in this area of east africa for generation show a high level of diversity in alleles for the fads gene. conversely, people whose families had migrated inland a moderate distance from sources of fish showed a much lower diversity for fads gene alleles. additionally, the fads alleles found in people whose family has lived inland for generation are almost all gene alleles which produce fads proteins with a high level of function and activity. how do anthropologists explain this?
