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 is a random change in allele frequencies in a population. It can lead to the loss of alleles, especially in small populations. When alleles are lost, the genetic variation within the population decreases. Mutations are random changes in DNA and are not directly caused by genetic drift. Gene flow is the transfer of genes between populations and is a separate evolutionary mechanism from genetic drift.

Answer:

decrease in genetic variation
