Sickle cell anemia is an inherited disease in which red blood cells become distorted and deprived of oxygen. A person with two sickle cell genes will have the disease, but a person with only one sickle cell gene will have a mild, non-fatal anemia called sickle cell trait.

Transcribed Image Text:Sickle cell anemia is an inherited disease in which red blood cells become distorted and
deprived of oxygen. A person with two sickle cell genes will have the disease, but a person
with only one sickle cell gene will have a mild, non-fatal anemia called sickle
cell trait. Using S to represent a healthy gene,
and s the sickle cell gene, the table shows the
four possibilities for the children of two Ss
parents. Find the probability that these parents
give birth to a child who is healthy.
That is, the child does not have the disease or
trait.
P(child is healthy) =
(Type an integer or a simplified fraction.)
