What is meant by 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. Give reason to justify your answer.

 

Answer:

Speciation is the process by which new species develop from existing species.

Factors that lead to speciation are:  

  • Genetic drift  
  • Mutation/ Drastic change in the genes or DNA  
  • Natural selection  
  • Geographical isolation

Geographical isolation cannot be a major factor in  the speciation of a self-pollinating plant species. This is because a physical geographical barrier cannot be created in self pollinating plants.
