When sickle cell carrier marries a normal woman, the probability of them having a normal offspring is A. 0.75 B. 0.25 C. 0.5 D. .1 Detailed SolutionA 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 = \(\frac{2}{4}\) = \(0.5\) There is an explanation video available below. |
