List three factors that could lead to speciation. Which of these cannot be a major factor in the speciation of a self-pollinating plant species and why?

Answer 1

Following are the factors responsible for speciation:-

1. Genetic drift
2. Natural selection
3. Mutation
4. Geographical isolation

A self-pollinating plant species cannot undergo significant diversification due to geographic isolation.

Reason: A physical barrier cannot be created in self pollinating plants.
