56 views

A baby's sex is determined by the chromosomes contributed by the parents. Typically, a mother provides an X chromosome, while a father can contribute either an X or a Y chromosome. If the baby receives an XX combination, it will be a girl; if it receives an XY combination, it will be a boy. This process happens at the moment of conception and is a natural part of genetic inheritance.
