2:Fertilization and
3:Post-fertilization
pre-fertilization: This stage invovles the event prior to fertilization .Gamete formation and transfer of gamete are the two processess that take place during the stage.Gamete are sex cell ,which are haploid in nature and are distinct in maled and females. The male gamete is called the sperm wherras the female gamete is called the ovum or egg
Fertilization : Once the haploid male and female gametes meet and fuse together to form a zygote, this is known as fertilization or syngamy. This can occur either outside the body called external fertilization or inside the body called internal fertilization.
Post-fertilization : : Fertilization results in diploid zygote formation. Eventually, the zygote divides mitotically and develops as an embryo. This process is called embryogenesis. During embryogenesis, cell differentiates and modifies accordingly. Zygote development depends on the organism and its life cycle.
