When sickle cell carrier marries a normal woman, the probability of them having a normal offspring is
0.75
0.25
0.5
0.1
Correct answer is C
A sickle cell carrier (AS) and a normal woman (AA), when crossed will yield: 2 normal offsprings (AA) and 2 sickle cell carrier (AS). Hence, the probability of a normal child = \(\frac{2}{4}\) = \(0.5\)
