Will geographical isolation be a major factor in the speciation of a self-pollinating plant species? Why or why not?
No, geographical isolation will not be the major factor in the speciation of the self pollinating plant species because geographical isolation is the part of the reproductive isolation which occurs before the mating of the individuals. Geographical isolation is the separation of a group of related organisms by physical barriers like sea, mountain, desserts etc. In the self pollinating plants new variants or new traits are not formed, only homozygous will form, but in cross pollination variations can evolve. So, geographical isolation cannot be the major factor in the speciation of self pollinating plants.
