Which of the following statements about sex determination is correct? At fertility
Answer Details
The statement that is correct about sex determination is "the probability of male to female offspring is 1/2". Sex determination is the process by which an individual develops into a male or female. In humans, it is determined by the combination of sex chromosomes received from the parents during fertilization. An egg from the mother always contains an X chromosome, while a sperm from the father may contain either an X or a Y chromosome. If the sperm carrying an X chromosome fertilizes the egg, the resulting offspring will be female (XX), and if the sperm carrying a Y chromosome fertilizes the egg, the resulting offspring will be male (XY). Therefore, the probability of having a male or female offspring is equal, and it is not influenced by the Y chromosome of the father or the XX chromosome of the mother. The vigour of either parent also does not determine the sex of the offspring.
