A sex-determination system is a biologicalsystem that determines the development of sexual characteristics in an organism. Most organisms that create their offspring using sexual reproduction have two sexes. Occasionally, there are hermaphrodites in place of one or both sexes. There are also some species that are only one sex due to parthenogenesis, the act of a female reproducing without fertilization.

in human 23 pairs of chromosomes are present. in these chromosomes one pair is known as sex chromosomes. in male XY chromosomes are present and in female XX chromosomes are present. during fertilization if male donates Y chromosomes then baby boy will born and if donates X Chromosomes then baby girl will born.
