Sex determination is often regulated by a master sex determination gene that initiates differentiation into a male or female. Among vertebrates, a wide variety of genes have been co-opted for this function, but how genes evolve novel functions in sex determination is not well understood. My research aims to identify the master sex determining gene in threespine stickleback (Gasterosteus aculeatus) and determine how this gene regulates conserved downstream elements in the sex differentiation pathway. My findings will provide insight into the mechanisms of vertebrate sex determination and how novel sex determination genes evolve.
