A couple are both carrier of sikle cell anemia. If they own two kids...?
A. What are the likelihood that one will be affected and the other not?
What is the likelihood that both will be carrier?
Answers: Sickle cell is an autosomal recessive trait.
So if they both are carriers, we can denote that as Ss, the capital is the normal gene, the lower grip is the sickle cell version.

The SS kid is ordinary. The 2 Ss kids are carriers, just like their parents. The ss kid get the short end of the stick and has sickle cell.
I'll let you figure out the rest from here. Source(s): college biology
The case have been well illustrated surrounded by the above answer, but the chances/risks of 25% normal, 50% trait carrier and 25% for sickle cell disease are for each child. The chance/risk for the second child are not contained by any way affected by that of the first child. So the couple could have adjectives normal, all trait carrier or adjectives sickle cell disease children. And I have seen couples with two or more children next to the disease, one normal and two with the disease as well as couples near two or more children all being trait carriers.
