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

Geographical isolation will not be a major factor in the speciation of an organism that reproduces asexually because it is a major factor in organisms that reproduces sexually.

No. Organisms which reproduce asexually, do not require mating or a partner for reproductive process. The reproduction process requires a single parent, that is the organism itself. Thus, geographical isolation does not affect the speciation process.

Geographical isolation will be a major factor in the speciation of an organism that reproduces sexually. It leads to the change in gene frequency leading to the expression of one type of traits in a geographically isolated population. In case of an asexually reproducing organism, geographical isolation cannot be a major factor is speciation because meiosis does not take place during asexual reproduction. Hence, there very rare chances of variation and without variation, there cannot be speciation.
