Question

Are the offspring of parents who are both homozygous dominant for normal red blood cells in danger of getting sickle-cell anemia?

Answer 1

Answer:

If both parents do not have sickle-cell anemia, than the possibility is low.

Explanation:

If both parents have the sickle-cell trait, their offspring has a 25 percent chance of getting sickle cell anemia and a 50 percent risk of them having sickle cell trait. Meanwhile, there is also a 25 percent chance of the child not getting it at all.

If one parent has sickle cell anemia and the other has sickle cell trait, then their offspring with have a 50 percent chance of getting sickle cell anemia and a 50 percent chance of getting a sickle cell trait.

When both parents have sickle cell anemia, their child will definitely have it.  

Answer 2

Answer:

No, 0% chance

Explanation:

none of the parents are carriers of this disease, and are homozygous dominant to the normal red blood cells, so they will not inherit this disease
