Describe the events (stages) that occur in sexual reproduction.

(N/A) After reaching maturity,all organisms that reproduce sexually exhibit various events and processes that show structural similarity,even though the structures associated with sexual reproduction differ significantly.
The events of sexual reproduction are complex and follow a regular sequence. The fusion of male and female gametes (fertilization),the formation of a zygote,and embryogenesis are characteristic features of sexual reproduction.
For convenience,these events are divided into three stages: Pre-fertilization events,Fertilization,and Post-fertilization events.
