Quizplus · Accepted Answer

The sex of the child is determined by the sperm of the father, which contains either an X or a Y chromosome. Therefore, the chance of having a son is determined solely by the father's genetic contribution and is not affected by the mother. Jack's chances of having a son with his new wife are the same as with his previous wife. However, it is important to note that the probability of having a son is approximately 50%, regardless of previous offspring.
