This chapter discusses the mechanism of sex determination in mammals. It is evident from the analysis of the sex determination pathway in non-mammals that there is a lack of mechanical or molecular conservation. Sex determination is one of the most diverse developmental pathways. Therefore, molecular data from these organisms cannot be extrapolated, for example, to clone mammalian sex.
