Genetic drift in a population affects the gene pool in which of the following ways? decrease in genetic variation
increase in genetic variation
increased in mutations
decreased in gene flow

Sometimes, there can be random fluctuations in the numbers of alleles in a population. These changes in relative allele frequency, called genetic drift, can either increase or decrease by chance over time. ... Genetic drift can result in the loss of rare alleles, and can decrease the size of the gene pool.
