- MALE
  - XY
  - Embryo
    - Gonadal Ridge at 6-7 weeks
      - Embryo
        NO SRY GENE PRESENT- No Y chromosome is present
        Mullerian duct and Ovaries
        The Mullerian duct develops as no testosterone or anti-mullerian substrate is present
        Wolfian ducts break down and so oviducts form
    - SRY GENE PRESENT -on the Y chromosome
      - This SRY gene acts as the master switch, it contains the testes determining factor, produces protein and where the HY antigen can befound
      - Wolfian duct and testes
        After 3 motnhs the Androgen testosterone and the anti mullerian substrate break down the mullerian ducts.
        Fetal Penis forms due to the introduction of testorone
