Question

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

Answer 1

Speciation:

Speciation is the process through which new species arise from the existing species.

Self-pollinating plant species and geographical barriers:

• Geographical isolation is the prevention of the gene flow among the group of population separated by a geographical barrier such as a mountain or a river.
• Self-pollination refers to the transfer of the pollen to the stigma of the same plant.
• Since mating takes place in a single plant and does not require the involvement of another plant, a geographical barrier does not affect self-pollinating plants.
