Reptiles have two modes of sex determination: genetic (GSD) and temperature dependent (TSD). We will determine if there is an underlying mechanism of sex determination common to TSD and GSD reptiles by comparing the genomes of two sister species of dragon lizard that differ in their mode of sex determination. This study will provide new insights to the mechanism of sex determination in vertebrates and will test the proposition that sex determination results from the interaction between environmental influences and an underlying genetic component.

爬行动物有两种性别决定方式：遗传（GSD）和温度依赖性（TSD）。我们将通过比较两种性别决定方式不同的姊妹物种龙蜥蜴的基因组，确定 TSD 和 GSD 爬行动物是否存在共同的性别决定机制。这项研究将为脊椎动物的性别决定机制提供新的见解，并将检验性别决定是环境影响与潜在遗传成分之间相互作用的结果的命题。
