feedback4="'''Correct!''' Gonadal differentiation is determined by the presence of the SRY gene of the Y chromosome (sex determining region of the Y chromosome) which encodes testicular determining factor protein (TDF). Lack of SRY gene (i.e. XX females) leads to ovarian differentiation. [[Reproductive Embryology Development - Pathology|WikiVet Article: Genital development]]"

feedback5="'''Incorrect.''' Presence of mesonephric ducts does not influence gonadal differentiation, they are primative structures present in the early embryo which will develop further or regress later in development. The correct answer is gonadal differentiation is determined by the presence of the SRY gene of the Y chromosome (sex determining region of the Y chromosome) which encodes testicular determining factor protein (TDF).

feedback2="'''Incorrect.''' Mullerian inhibitory substance is produced by the testes and induces development of the mesonephric (Wolffian) duct system in to epididymis and vas deferens and causes regression of paramesonephric (Mullerian) duct.
