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:- It is formation of new and distinct species in course of evolution

#The four factors that could lead to speciation:-
1. Reproduction isolation
2. Genetic drift
3. Geographical isolation
4. Natural selection

#Reason:-
In case of plant species with self pollinating flowers the factor reproducing isolation will not have much effect because the plant is not dependent on any other species for reproduction but has male and female parts in same flower or plant. Thus there is no effect of reproducing isolation.

Answer 2

hello dear
the process in which the new species develop from the existing species is called speciation
the four factor is
1. geograpical isolation
2. genetic drift
3. natural selection
4. reproduction isolation
geograpical isolation cannot be major fector in the speciation
because it does not cause any variation
