Which of the following is a mechanism of evolution that involves random changes in allele frequencies? (1985)

Step 1: Understand what evolution means. Evolution is the process by which species change over time.
Step 2: Learn about allele frequencies. Alleles are different versions of a gene, and allele frequency is how common an allele is in a population.
Step 3: Identify mechanisms of evolution. There are several mechanisms, including natural selection, mutation, gene flow, and genetic drift.
Step 4: Focus on genetic drift. Genetic drift is a mechanism that causes random changes in allele frequencies, especially in small populations.
Step 5: Conclude that genetic drift is the correct answer to the question about random changes in allele frequencies.
