What is speciation? List four factors that could lead to speciation. Which of these cannot be a major factor in the speciation of a self-pollinating plant species? Explain. Give reason to justify your answer.
Answer:
Speciation is the formation of new species from the pre-existing population.
Factors responsible for speciation:
- Genetic drift
- Natural selection
- Geographical isolation
- Mutation
Geographical isolation cannot be a major factor in the speciation of a self pollinating plant species because physical barrier cannot be created in self-pollinating plants.
