Although each of the following has a better chance of influencing gene frequencies in small populations than in large population
MakcuM [25]

Answer:

genetic drift

Explanation:

Genetic drift is an evolutionary force that requires the presence of a small population. It is a random process that fixes one or other alleles randomly in the gene pool of a population. Genetic drift does not take account of survival fitness imparted by alleles to the individuals. Since random and chance events such as the death of all the individuals having a certain allele in a population affect the small population more intensely, genetic drift works on small populations only.
