Will geographical isolation be a major f | Class 10 Science Chapter Heredity and Evolution, Heredity and Evolution NCERT Solutions

Question:

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

Answer:

Asexual reproduction occurs during the formation of two daughter cells from one parent only. There will be no variation when there is only one parent involved. And, where there is no variation speciation cannot occur. As in the self pollinating flowers geographical isolation is not the major factor in the speciation, this can also be seen in the case of asexual reproducing organisms. Where there is no variation, competition or genetic recombination, speciation will not occur and as well as geographical isolation will not occur because it refers to the separation of group of related organisms by some barriers.
