In spite of their morphological, anatomical and physiological differences, the fundamental events in sexual reproduction are the same. These events can be categorized as follows:
1. Pre-fertilization events: All the preparatory events which occur before the fusion of gametes are called pre-fertilization events. These include gametogenesis and gamete transfer.
2. Fertilization: Fusion of two entire gametes ( one male and another female) to form a zygote.
3. Post-fertilization: All the events that occur during sexual reproduction after the fusion of gametes are called post-fertilization events.
