Answer:

1. Nuclei

2. is contributed equally

Step-by-step 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. This shows that it is the fusion of nuclei in important as genetic material is present in the nucleus. After the fusion, a diploid zygote is formed in which the genetic material is contributed equally by both the parents through gametes.
