Which Process Below is NOT an Agent of Microevolutionary Change

Question

Which process below is NOT an agent of microevolutionary change?
A) mutation
B) genetic drift
C) natural selection
D) random mating

Accepted Answer

Random mating does not cause microevolutionary change; instead, it maintains genetic diversity without changing the population's allele frequencies. Mutation, genetic drift, and natural selection directly contribute to changes in allele frequencies within a population, driving microevolution.
