COLORADO GARZON, FREDY A; MATTA CAMACHO, NUBIA E  and  SANCHEZ, ANTONIO. SEX-DETERMINATION SYSTEMS AND THEIR EVOLUTION: MAMMALS. Acta biol.Colomb. [online]. 2012, vol.17, n.1, pp.3-18. ISSN 0120-548X.

Sex-determination methods are very diverse as they have become an enduring research field. Understanding the causes of gonadal development and elucidating the main factors involved in sex-determination of offspring required relating information from far-ranging areas such as cytology, embryology, morphology, molecular biology and even ecology and evolution. This article presents an overview of sex-determination in placental mammals, encompassing several levels of biological organization. The importance of the underlying molecular tools in the context of sex-determination assays and their implications in conservation genetics is also discussed.

Keywords : Sex chromosomes; SRY-HMG; sexual reversion; genetic conservation and sex-determination.
