Detailed explanation-1: -The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female’s reproductive system. When sperm fertilizes (meets) an egg, this fertilized egg is called a zygote (ZYE-goat). The zygote goes through a process of becoming an embryo and developing into a fetus.

Detailed explanation-2: -Egg and sperm cells have just 23 chromosomes each. That’s half as many chromosomes as regular cells. Through the process of fertilization, egg and sperm join to make a cell with 46 chromosomes (23 pairs), called a zygote.

Detailed explanation-3: -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.

Detailed explanation-4: -Fertilisation. Fertilization is the process of fusion of male sex cell (pollen) and the female sex cell in the flower of a plant which results in the formation of fruits. The cell formed by the fusion of the male and female sex cell is the zygote.
