This is the result of fertilization, in the early stages of growth and development

The result of fertilization is a cell (zygote) capable of undergoing cell division to form a new individual. The fusion of two gametes initiates several reactions in the egg ... The most important result of fertilization is egg activation, which allows the egg to undergo cell division. Fertilization is the process in which haploid gametes fuse to form a diploid cell called a zygote. To ensure that each zygote has the correct number of chromosomes, only one sperm can fuse with one egg.

Cell or zygote is the product of the fertilization process.

Explanation:

Zygote is formed by the fusion of sperm cells of male and egg cells of female in the process of fertilization. Zygote is diploid cell i. e. double number of chromosomes while male sperm cell and female egg cell are haploid i. e. half number of chromosome. Zygote contains half genes from father and half from mother cell.
