Will geographical isolation be a major factor in the speciation of a self-pollinating plant species? Why or why not
Geographical isolation prevents transfer of genes between two species. In self-pollinating plant, pollen is transferred from the anther of one flower to the stigma of the same flower or of another flower of the same plant. It does not require any external agent for pollination, neither is it dependant on another plant for pollination. So, geographical isolation cannot affect the speciation of a self-pollinating plant.
