Question

Mr. and Mrs. S have just married. They are healthy, but the husband's brother has two boys with sickle cell anemia and the wife's sister has the same disease. Sickle cell anemia is a condition in which there arent enough healthy red blood cells to carry adequate oxygen throughout your body. They are considering having children and have sought the advice of a genetic counselor. What are the chances of a child with the disorder?

Answer 1

Answer: Your welcome!

Step-by-step explanation:

The chances of having a child with the disorder depend on the genetic makeup of Mr. and Mrs. S. If both Mr. and Mrs. S are carriers of the sickle cell anemia gene, then the chances of having a child with the disorder are 25%. This is because both parents would need to pass on the genetic mutation to their child, and since both have it, there is a 25% chance of passing it on to their child. If only one of the parents is a carrier, then the chances are much lower at 12.5%.

It is important to note that there is no guarantee that a child will or will not have the disorder, as there are other factors that can influence the outcome. It is recommended that Mr. and Mrs. S seek the advice of a genetic counselor to better understand their risks and potential outcomes.
