Question
List four factors that could lead to speciation. Which of them cannot be a major factor in the speciation of a self-pollinating plant species?. Give reason to justify your answer.
Solution
Following are the factors responsible for speciation:-
1. Genetic drift
2. Natural selection
3. Reproductive isolation
4. Geographical isolation
Reproductive isolation is not a major factor in the speciation of a self-pollinating plant species because reproductive isolation refers to the absence of other reproductively compatible plants in the same area. A self-pollinating plant species is not dependent on other compatible plants for pollen transfer.
