What is meant 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?
Answers
Specification is the process by which new species develop from the existing species.
The four factors that lead to specification are:
1.Genetic drift
2.Mutation
3.Natural selection
4.Migration
out of the following, geographical isolation will not be a major factor in the specification of a self-pollinating plant species.
The formation of a new species by evolution or by any genetic modification of the previously existing species in a population is called speciation. Following are the factors that could lead to speciation: 1. Geographic isolation 2. Reproductive isolation 3. Genetic drift 4. Natural selection
Geographical isolation can not be a major factor in the speciation of a self-pollinating plant species. Since, the plants are self-pollinating, which means that the pollens are transferred from the anther of one flower to the stigma of the same flower or to the stigma of another flower of the same plant, geographical isolation cannot prevent speciation in this case.
