Question

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

Answer 1

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.

Answer 2

The production of a new species from two different species is known as speciation.

Factors responsible for it are:-

1)Natural selection:-Due some natural incidents ,there are genetic variations in new individuals,which led to evolving of new species.

2)Genetic drift:-Sudden alternation in gene frequency is called genetic drift

3)Survival advantage:-Due to camouflage some species enjoy the survival advantage.

4)Migration:-Migration of differnt species also led to evolvement of new species.
