Question 4: Short Answer and Predicting Outcomes: Chemical Signals and Reproduction, 14 points Write short responses to each of the questions below. Each of your answers should explain the answer fully in 1-2 sentences. Testosterone is an example of a steroid hormone that has effects on the very cell that produced it, adjacent cells in the gonad, as well as different tissues outside of the gonad. This hormone can have major effects on reproductive development and sex determination. What types of signaling can testosterone be involved in (hint – the first sentence of this question’s explanation)? (2 pts) How is the production of testosterone regulated? (2 pts) How is testosterone signaling regulated? (2 pts) How is the specificity of the testosterone signal ensured? (2 pts) What is the ultimate result of testosterone signaling on a target cell? (2 pts) What would be the result of blocking testosterone signaling in a genotypically male developing vertebrate that uses genetic sex determination? (2 pts) What would be the result of reducing Cyp19a1 aromatase expression in a genotypically female developing vertebrate that uses genetic sex determination? (2 pts)
