Question

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

Explanation:

Genetic drift refers to random changes in allele frequencies in a population. In small populations, genetic drift can lead to the loss of alleles, reducing genetic variation. Mutations are random changes in DNA and are not directly caused by genetic drift. Gene flow is the transfer of alleles between populations and is a separate evolutionary mechanism. Genetic drift does not increase genetic variation.

Answer:

decrease in genetic variation
