Final answer:
Genetic cloning is not an evolutionary force; instead, mutation, gene flow, genetic drift, and natural selection are the forces that naturally affect allele frequencies in a population's gene pool.
Step-by-step explanation:
All of the following are Evolutionary Forces except genetic cloning. Genetic cloning is not considered a natural evolutionary force; rather, it is a technological process used to create genetically identical copies of an organism or its cells. The four primary forces of evolution that affect allele frequencies naturally within a population's gene pool are mutation, gene flow, genetic drift, and natural selection. Mutation introduces new genetic variation, gene flow occurs when alleles are transferred through the movement of individuals or gametes between populations, and genetic drift is the random fluctuation of allele frequencies over time. These processes can all impact a population's genetic makeup.
