Question

Will geographical isolation be a major factor in the speciation of an organism that reproduces asexually? Why or why not? [3 MARKS]

Answer 1

Each point: 1 Mark

1. Geographical isolation prevents gene flow between populations of a species whereas asexual reproduction generally involves only one individual.
2. In an asexually reproducing organism, variations can occur only when the copying of DNA is not accurate.
3. Therefore, geographical isolation cannot prevent the formation of new species in asexually reproducing organism.
