Baby's gender is determined at fertilization when the chromosomes from mother and father combine.
The mother always contributes an egg cell carrying an X chromosome. The sperm cell from the father carries either an X or Y chromosome. If the sperm carries an X chromosome, the result is XX and the baby is female; if the sperm carries a Y chromosome, the result is XY and the baby is male.
In other words, the main factor determining gender is which sperm fertilizes the egg—this is entirely a genetic process and cannot be controlled by any parental preference, behavior, or external factor. It becomes visible on ultrasound around weeks 16-20 of pregnancy.
