Question

What is speciation? What are the factors of speciation? Will geographical barrier is a major factor in speciation of a self-pollinating plant species?

Answer 1

The process of development of a new species by evolution or by any genetic modification of the existing species in a population is called as speciation. Factors that lead to speciation include genetic drift, natural selection, geographical isolation, mutation. Geographical isolation is not a major factor in the speciation of a self-pollinating plant species as pollination occurs between the reproductive organs of the same flower.
