In a family of eight (8) all the children are girls Which of the following reasons correctly explains this?

Answer Details

The reason that correctly explains why all the children in a family of eight (8) are girls is that the sperm of the father carried only the X chromosome. In humans, the sex of an individual is determined by the sex chromosomes contributed by the parents during fertilization. Females have two X chromosomes (XX) while males have one X and one Y chromosome (XY). The father in this case must have produced sperm carrying only the X chromosome, which when fertilized with the mother's X chromosome, produced only female offspring. This is a rare occurrence, but it can happen due to random chance. The other options presented in the question are possible causes of having fewer male offspring, but they do not explain the specific scenario described in the question where all the children are girls.
