If two people with sickle cell trait have children, what is thechance that a child will have normal RBCs in both high-and low-ox
Vanyuwa [196]

Answer:

See the answer below

Explanation:

<em>The chance that a child from two people with sickle cell trait will have normal RBCs remains the same irrespective of the amount of oxygen in the environment.</em> From the cross:

                  AS    x    AS

            AA    AS    AS    SS

Hence, the chance of having a child with normal RBCs in both high and low-oxygen environments is 1/4 or 25%.

The chance that a child will have sickle cell disease is also 1/4   or 25%.
