Explanation / Answer
As per Mendelian Laws of Inheritance (Segregation, Independent Assortment, and Dominance), we get:
The 23rd chromosome determines the sex of the child.
If it is XY then male, if XX then female.
Hence the female mother is XX and always donates the X chromosome to the offspring,
while, the male father is XY and can donate an X chromosome to form a female, or donate an Y chromosome to form a male.
Hence, because of this mechanism, there is always a 50% chance to get either a male or a female child.
Hence, even the world population reflects the same.
By randomly selecting 100 families that only have one child, we can expect 50 families to have a child that is a boy, and 50 families to have a child that is a girl.
