25 views

Gender is determined by the 23rd pair of chromosomes. Females have two X chromosomes (XX), while males have one X and one Y chromosome (XY). The presence of the Y chromosome triggers male development. During reproduction, the sperm contributes either an X or a Y chromosome, determining the sex of the offspring.

  2. Can gender be influenced by chromosomes other than the 23rd pair? While the 23rd pair is the primary determinant of gender, other genetic factors can also play a role in sexual development.
  3. How many chromosomes do humans have? Humans typically have 46 chromosomes, arranged in 23 pairs.
  4. What are the implications of chromosomal abnormalities on gender? Chromosomal abnormalities can lead to various intersex conditions, affecting gender development.
