Q. Will geographical isolation be a major factor in the speciation of an organism that reproduces asexually? Why or why not? 

 

Answer:-



No, in asexually reproducing organisms there is very little variation over generations. Asexual reproduction does not require two organisms to reproduce as variations in the DNA are not enough to raise a new species. Thus geographical isolation is not a major factor As asexual reproduction is carried out within the same organism, resulting organism in next generation will have identical copies of DNA, so there will be very less genetic variant to be a cause of the speciation of an organism. Geographical isolation can become a major contributory factor if is increases chances for a change to develop in gene flow (Genetic drift), leading to formation of a new species.
