Genetic Drift May Lead To

Question

Genetic drift may lead to
A)loss of genetic variation in a population.
B)a decrease in the mutation rate of a particular gene.
C)increased heterozygosity at many loci.

Accepted Answer

Genetic drift is a random process that can lead to the loss of certain alleles or genetic variants in a population. This can result in a decrease in genetic variation within the population over time. Therefore, option A is the best choice. Option B is incorrect because genetic drift has no effect on mutation rates. Option C is also incorrect because genetic drift can actually decrease heterozygosity by chance events (such as a small group of individuals starting a new population).
