Hello, here’s the answer
Sex is determined in the unborn baby by identifying the set of 46 chromosomes which comprises of 23 X chromosomes received from the mother’s egg cell and 23 X or Y chromosomes received from the father’s sperm cell. If the set has 46 X chromosomes, then the unborn baby is a girl and if the set Has 23 X and 23 Y chromosomes, then the unborn baby is a boy. So, it depends 50-50 upon the chromosomes of father’s sperm cell whether the unborn baby will be a boy or a girl.
