本文研究了具有温度依赖性性别决定作用的龟类Trachemys scripta的温度敏感性和性腺分化。性别决定对孵化温度的长短和大小都很敏感。温度对大多数性腺的卵巢或睾丸性质产生了“全或无”的影响，但以分级的方式影响卵巢的长度。总的来说，结果表明，性别决定是由温度的定量效应在一段时间内开始之前（组织学检测）的性分化，并延长到一个时间时，最初的性别特异性变化是明显的性腺。
Temperature sensitivity and gonadal differentiation were studied in a turtle, Trachemys scripta, with temperature-dependent sex determination. Sex determination was sensitive to both the duration and magnitude of incubation temperature. Temperature exerted an "all or none" effect on the ovarian or testicular nature of most gonads, but affected the length of ovaries in a graded fashion. Collectively, the results indicate that sex determination is controlled by the quantitative effect of temperature during a period beginning prior to (histologically detectable) sexual differentiation and extending to a time when initial sex specific changes are evident in the gonads.
