Answer:
B) Random fluctuations in the gene frequencies within a population
Explanation:
Genetic drift is one of the evolutionary process that deviated the population from Hardy–Weinberg equilibrium. Genetic drift refers to the change in the allele frequency of population due to chance event alone. It does not include natural selection or gene transfer. It brings out random change in allele frequency in the population. Genetic drift is more effective in a small breeding population.
