Question

Which factor listed below most likely results in the loss of genetic variation from small populations by having a random change in allele frequency? A.migration B.mutation C. genetic drift

Answer 1

Migration results in the loss of genetic variation from small populations by having a random change in allele frequency.

Answer 2

I believe the answer is: Genetic Drift

The change in allele frequency usually caused by the population that have a certain allele structure somehow unable to survive in the environment. This cause a certain genetic variation to be reduced from the population which make the organisms within it become more similar.
