1.	How would the gene flow or genetic drift affect the population in which either of them happens to take place?
Answer» Genetic drift refers to the alteration in the frequencies of alleles in the gene pool of a finite population due to chance events. It takes place in one or over a few generations. If the change in the allele frequencies is very drastic, then new species are formed. If the population is finite or limited, a random selection of alleles occurs and in such a scenario, the frequencies of alleles in a sample may not be the same as the frequencies of alleles in the total population. This is known as sampling error.
