Does the SRY Gene Code for Testosterone? Explained

Learn why the SRY gene does not code for testosterone but triggers male sex determination through testes development.

216 views

No, the SRY gene does not code for testosterone. The SRY gene, located on the Y chromosome, is responsible for initiating male sex determination by producing the SRY protein. This protein triggers the development of testes, which subsequently produce testosterone and other male hormones. The actual production of testosterone is managed by enzymes within the testes, not by the SRY gene itself.

FAQs & Answers

  1. What is the function of the SRY gene? The SRY gene initiates male sex determination by producing the SRY protein, which triggers the development of testes.
  2. Does the SRY gene produce testosterone? No, the SRY gene does not produce testosterone; instead, it triggers testes development, which then produce testosterone.
  3. How is testosterone produced in the male body? Testosterone is produced by enzymes within the testes, following the developmental signals initiated by the SRY gene.
  4. Where is the SRY gene located? The SRY gene is located on the Y chromosome.
