Answer:
The potential parental genotypes could be "both recessive" or "both heterozygous".
Step-by-step explanation:
Sickle cell anemia is a disease where there are not enough red blood cells throughout the body so they are not able to carry the necessary amount of oxygen for the body to function properly. It is a disease that is carried on recessive genes so for an individual to have this disorder, they must have to recessive genes from both parents. In this case the potential parental genotypes could be "both recessive" or "both heterozygous".
I hope this answer helps.
