Solution
The correct option is B Genetic drift
Genetic drift is the random change in the frequency of alleles in a population over successive generations in the gametes. Each new generation differs from its parental generation with regard to allele frequencies simply because of random variation in the random distribution of gametes. This process is more rapid in smaller populations, or when the alleles are concerned to confer no apparent benefit compared to their counterparts.
