उत्तर
The fusion of the male and the female gametes is called fertilisation.
Explanation:
The process of fusion of a sperm with an ovum is called fertilisation. During fertilisation, a sperm comes into contact with the zona pellucida layer of the ovum and induces changes in the membrane that block the entry of additional sperms. Thus, it ensures that only one sperm can fertilise an ovum.
