Solution and Explanation
Sex chromosomes determine the biological sex of an individual. In humans, there are two types:
- X chromosome
- Y chromosome
Sex Determination Process:
- Males have XY chromosomes, and females have XX.
- The sex of the child depends on the type of sperm (X or Y) fertilizing the egg.
- If an X-sperm fertilizes the egg, a female (XX) is formed.
- If a Y-sperm fertilizes the egg, a male (XY) is formed.
- X chromosome
