Question

5. In Genetic Drift Beetles, the genetic drift event reduces the beetle population size to two beetles at random. Once the beetle population is smaller, which force of evolution takes over to cause changes in allele frequency in the next generations? *

1) non-random mating
2) gene flow
3) genetic drift (small population)
4) mutations
5) natural selection (adaptation)

Answer 1

3) genetic drift (small population)

I hope this helps you
