Graduate Theses and Dissertations

Sex determination mechanisms (SDMs) direct the development of individuals towards a male or female fate, and in vertebrates they are typically controlled by an individual’s genotypic content (genotypic sex determination, GSD) or through an environmental cue experienced during development, mainly temperature (temperature-dependent sex determination, TSD). Among vertebrates, SDMs are surprisingly labile, transitioning between different forms of TSD and GSD in some lineages more than others. Turtles represent a model clade to study SDM evolution, as multiple independent transitions between TSD and GSD have occurred throughout their evolution and a growing number of genomic datasets have become available.
