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.

- 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.
- How many chromosomes do humans have? Humans typically have 46 chromosomes, arranged in 23 pairs.
