Will geographical isolation be a major factor in the speciation of a self-pollinating plant species? Why or why not?




Self pollination involves transfer of pollen from the anther (male reproductive part) to the stigma (female reproductive part) of the same flower .


  • Since only 1 flower is involved , it does not require the presence of another flower in the vicinity for pollination.
  • Thus, geographical isolation is not a major factor in the speciation of a self- pollinating plant species.
