性别分化是一个极其复杂的个体发育过程。性别与其他性状的出现一样,都是遗传因素和环境条件相互作用的结果。当内外环境有利于某一种性别的发育时,就有可能偏离性别决定的方向,形成不正常的雄体或雌体。现在已知道,能使性别分化偏离性别决定方向的因素有温度、阳光、营养条件、性激素等,它们通过影响有关性别决定基因的活动来发挥作用。但这些因素只能影响性别性状,不能改变性别的遗传组成。
Therefore, the experimental method of adding gonadal hormone to tadpole feed can induce the sex differentiation and promote the growth of tadpole. It is feasible to control the sex of Rana temporara chensinensis.

当然,这一研究并不能对名字和性别一概而论,尤其考虑到性别并不能分化成两极来谈。
Of course, this study isn't the end of all conversations about names and gender, especially considering how gender can't be simplified between just two ends of a spectrum.
