Question

Which is true about the dad?

1) His genotype is ss.
2) He is a carrier of sickle cell.
3) He likely has the typical S S of sickle cell.
4) All of the above.

Answer 1

The true statement about the dad is that he is a carrier of sickle cell if he has children with the disease and does not exhibit symptoms himself, which means he has an Ss genotype.

Step-by-step explanation:

Regarding the statement about the dad in a sickle cell anemia context, the correct option is that he is a carrier of sickle cell if we assume he has children with the sickle cell disease and he does not exhibit symptoms. Here's why: A person with genotype ss has sickle cell anemia, not just the trait, which means that all of their red blood cells have the incorrect hemoglobin and are misshapen. A carrier of sickle cell, which means they have the sickle cell trait without the disease, would have the genotype Ss. This means they have some normal red blood cells and some sickle-shaped cells. The genotype SS would result in a person having all typical, round red blood cells. Since carriers are typically asymptomatic, a father with an Ss genotype would not show the symptoms of sickle cell anemia, but could still pass the recessive sickle cell allele to his offspring.
