14. Pat and Tracy each have a sibling who has the recessive trait of sickle cell disorder. Neither Pat. Tracy or
Nady [450]

Answer:

Since sickle cell disease is a disorder with an autosomal dominant inheritance pattern, and in light of the lack of data, it could be said that the only way for Pat and Tracy to have a child with sickle cell disease is for both of them to be healthy carriers of the gene, with a 25% probability.

Explanation:

Considering that both Pat and Tracy each have a sibling with a sickle cell trait and that both they and their parents are healthy, it must be assumed that some of their parents are healthy carriers:

  1. Pat and Tracy do not have sickle cell trait. In this case, there is no chance that they will have a child with sickle cell disease.
  2. Either Pat or Tracy has the trait, but the other does not. It is possible that at least one of their children is a healthy carrier.
  3. If both Tracy and Pat have sickle cell trait, the chances of having a child with sickle cell disease are:

Alelles       R         r

R              RR       Rr

r               Rr        rr

RR: healthy (25%).

Rr:  healthy carrier (50%).

rr: sickle cell disease (25%).

<em>If Pat and Tracy are healthy carriers of the gene that determines sickle cell disease, the chance of having a child with the disease is 25%</em>.
