Explanation:

Zona pellucida layer of the ovum prevents polyspermy in humans. It induces changes in the membrane of the ovum to block the entry of additional sperms, thereby ensuring the entry of only one sperm inside the ovum.

Answer:

[Heyaa mate...When a sperm comes in contact with the zona pellucida layer of the ovum, it induces changes in the membrane of the ovum to block the entry of additional sperms. This, thus, prevents the polyspermy and ensures that only one sperm can fertilise an ovum.]
