Answer:
Genetic drift produces a species in just a few generation.
Explanation:
Genetic drift means change in the gene frequency in a population due to random sampling of an organism.The allele of the sample in the parents has a role that determines the survival and reproduction of the organism.Allele frequency is the copy of gene which shares a particular form.Thus those speciation which occur due to genetic drift will produce species in just few generations.
The effect of genetic drift is larger and is acting on neutral mutation.
