Sexual differentiation of the gonads in Alligator mississippiensis and many other oviparous
reptiles is controlled by egg incubation temperature. Estrogens are thought to play a role in …

In all species of crocodilians, sex is determined not by genetic mechanisms, but by the
temperature at which the egg is incubated. In the American alligator (Alligator …

The leading explanation of temperature-dependent sex determination (TSD) in reptiles
postulates that (1) ovarian differentiation is directed by estrogen and that (2) estrogen is …

During embryogenesis, incubation temperature and the hormonal environment influence
gonadal differentiation of some reptiles, including all crocodilians. Current evidence …

It has been suggested that sex differentiation in vertebrates is steroid hormone dependent,
that estrogens play a critical role in ovarian differentiation, and that male sex differentiation …

It has been hypothesized that estrogen production may play a pivotal role in the sex
determination of reptiles with temperature-dependent sex determination (TSD). This …

Sex determination in egg‐laying amniotes may be fundamentally different from that of
placental mammals. The mammalian ovary differentiates normally in the absence of …

A brief review of our current understanding (or lack of understanding) of the molecular basis
of temperature‐dependent sex determination (TSD) in reptiles is presented. Current theories …

In many species of reptiles, sex is determined at fertilization by zygotic sex chromosome
composition. In other species, including all crocodilians, most turtles and some lizards, sex is …

In the diamondback terrapin, Malaclemys terrapin, males hatch at incubation temperatures
below 28° C whereas females hatch at temperatures above 30° C. When estrogen is applied …
