Quizplus · Accepted Answer

The testis-determining factor (TDF) is a gene located on the Y chromosome that initiates the development of male gonads in mammals. TDF directs a series of events that lead to the differentiation of the undifferentiated gonad to the male form, including the development of testes, production of testosterone, and development of male secondary sexual characteristics.
