Figure 4. Percentage of males in groups treated with cortisol and the synthetic glucocorticoid receptor (GR) agonist Dexamethasone.

All groups were reared at an intermediate temperature (24°C) during the trials. Groups treated with cortisol and Dexamethasone had increased proportions of males compared to the respective controls. Numbers within parenthesis indicate the sample number; asterisks indicate statistically significant differences between groups in the same trial (χ²; P≤0.05; GraphPad Prism v.4.00).
