Genetic drift is the change in the number of organisms in a population due to other factors like an earthquake or a disease.
like in a area there are 100 beetle. 80are red and 20 are blue. in an earthquake all the blue batele are dead so only red are left , only they can survive.
Geographical isolation is the geographical barriers which saperate or isolate two population of same species and form two new species. because genes were not transfer in both population.
