Concepts Used:
Sexual Reproduction
Sexual reproduction takes place in both plants and animals. In sexual reproduction, genetically diverse organisms or sphinx are built this happens when two individuals of unique sex are combined.
The offspring built by sexual reproduction are genetically diverse in nature and can embrace themselves in accordance with the climate and other adaptable conditions many multicellular organisms practice sexual reproduction.
There are four types of sexual reproduction:
- Allogamy
- Internal fertilization
- External fertilization
- Autogamy
