The male DNA code includes the presence of one X chromosome and one Y chromosome (XY). This Y chromosome contains specific genes, like SRY, that direct the development of male physical characteristics.

FAQs & Answers

  1. What chromosomes determine male DNA? Male DNA is determined by the presence of one X chromosome and one Y chromosome (XY).
  2. What is the role of the SRY gene in males? The SRY gene on the Y chromosome directs the development of male physical characteristics.
  3. How does the Y chromosome affect male development? The Y chromosome carries genes like SRY that trigger the biological process leading to male sex differentiation.
