In a random mating population in equilibrium, which of the following brings about a change in gene frequency in non-directional manner?

Selection

Migration

Mutation

Random drift

Solution

Given certain conditions, the allele frequencies remain constant from generation to generation. Under these conditions, a population would be in equilibrium and there will be no evolutionary change. However, many evolutionary changes usually occurs, following the appearance of new alleles and source of this mutation.
