Biological sex is determined by chromosomes; typically, males have XY chromosomes, while females have XX chromosomes. In addition, hormonal levels and anatomical features also play significant roles in determining gender.

FAQs & Answers

  1. What are the differences between XY and XX chromosomes? XY chromosomes typically define male biological traits, while XX chromosomes define female traits, affecting physical development.
  2. How do hormones influence gender determination? Hormones like testosterone and estrogen play crucial roles in the development of secondary sexual characteristics in males and females.
  3. Can environmental factors affect biological sex? While genetics primarily determine sex, certain environmental factors can influence hormonal levels during development.
  4. What roles do anatomy and physiology play in gender? Anatomical structures, such as reproductive organs, and physiological processes are vital in differentiating male and female bodies.
