Representation of the ZZ and ZW genes in males and females and gonadal development. The Anti-Mullerian hormone has a significant role in males by inhibiting the SF1 gene. In females, the SF1 gene is less inhibited, forming several proteins (3β-HSD, P450arom and 17β-HSD), fundamental for the estrogens-related products (e.g., 17β-E2 or estrone-3-sulfate). Until d 3.5 of incubation, there is no sexual differentiation, whereas gene expression and hormonal presence differences are noticed after this moment [68, 69].
