Genetic drift in a population affects the gene pool in which of the following ways?
A. decrease in genetic variation
B. increase in genetic variation
C. increased in mutations
D. decreased in gene flow
Answer (2)
Genetic drift leads to a decrease in genetic variation by causing random changes in allele frequencies, particularly in small populations. This reduction can limit the population’s adaptability. The correct answer to the question is a decrease in genetic variation. ;
Genetic drift causes random changes in allele frequencies within a population, leading to a decrease in genetic variation. This is particularly impactful in small populations where certain alleles may become lost entirely. Therefore, the correct answer is a decrease in genetic variation.
