Question:
(b) In a human female, probability of an ovum to get fertilized by more than one sperm is impossible. Give reason.
(b) In a human female, probability of an ovum to get fertilized by more than one sperm is impossible. Give reason.
Show Hint
The fertilization membrane is a key defense mechanism to ensure only one sperm fertilizes the ovum, preventing polyspermy.

Solution and Explanation
- Once a sperm penetrates the ovum, a chemical reaction occurs, forming a fertilization membrane.
- This fertilization membrane prevents the entry of additional sperms, ensuring monospermy.
