Explanation:
Once fertilized, the egg is called a zygote. Fertilization is not complete, however, until the two haploid nuclei (called pronuclei) have come together and combined their chromosomes into a single diploid nucleus. In fertilized mammalian eggs, the two pronuclei do not fuse directly as they do in many other species.
Answer:
The union of a sperm cell and an egg cell is called fertilization. The fertilized egg, which results from this process, is called a zygote. After fertilization, the zygote undergoes multiple cell divisions and eventually forms a blastocyst, which implants itself into the uterus during the process of implantation.
