2. is contributed equally
Explanation:
Fertilization is a process which involves the fusion of the two opposite sex gametes during sexual reproduction. The male gamete is known as the sperm while the female gamete is known as the egg.
If we look into the microscopy of the fertilization process, we will find that the process involves the fusion of gametes involves the fusion of the nuclei.
