Which of the following do you expect if an individual is heterozygous for the sickle-cell trait? see conceptA. they will not develop sickle-cell diseaseB. they will show some symptoms of the disease because the allele that causes sickle-cell disease is not really recessiveC. they will be more apt to acquire a serious case of malariaD. they will have full-blown sickle-cell disease because the allele is dominantE. none of the listed choices are correct

Respuesta :

An individual who is heterozygous for the sickle-cell trait will display some disease symptoms (Option-b). It is a widespread illness.

The sickle cell trait is what?

Red blood cells with sickle cell disease are distorted, losing their characteristic circular shape.

Sickle cell disease is a genetic condition brought on by mutations that can be passed down through the generations.

Because sickle cell disease is a codominant condition, heterozygous people who have both normal and defective alleles express it.

Therefore, compared to normal homozygotes, heterozygotes are more resistant to the incapacitating effects of malaria. In many sickle-cell carriers, this heterozygote advantage outweighs the severe reproductive disadvantage of the more uncommon sickle-cell homozygotes.
