New alleles can be introduced into a population's gene pool by:_________?
Correct answer: D. Both A & C
- A. Mutation
- B. Natural selection
- C. Gene flow
- D. Both A & C
Explanation
Mutation creates new alleles, while gene flow can introduce alleles from another population. Natural selection changes the frequencies of existing alleles but does not itself create new alleles, so both A and C are correct.

About Concept of Evolution
Evolution is the heritable change in populations over generations, driven by mutation, recombination, natural selection, genetic drift and reproductive isolation. Questions examine variation, adaptation, survival and reproduction, speciation, fossil and anatomical evidence, and the difference between individual acclimatization and evolutionary change in a population.
