The Y chromosome gene is a primary indicator of gender. Presence of a Y chromosome typically results in a male, while its absence (having two X chromosomes) results in a female. Key genes like SRY on the Y chromosome play crucial roles in male differentiation.

FAQs & Answers

  1. What role does the SRY gene play in gender determination? The SRY gene on the Y chromosome is crucial for male differentiation, triggering the development of male characteristics.
  2. Can gender be determined without a Y chromosome? Yes, the presence of two X chromosomes typically results in female characteristics, while the Y chromosome generally indicates male.
  3. Are there exceptions to the typical gender chromosomal patterns? Yes, various intersex conditions can lead to atypical chromosomal expressions affecting gender development.
  4. How does genetics influence gender beyond chromosomes? Environmental factors, hormone levels, and genetic variations also play significant roles in gender development and expression.
