Which term would a biologist use to describe the total genetic variation present in a population?

• A. Gene Pool
• B. Autotroph
• C. Comparative Embryology
• D. Descent with Modification

Answer: (A)

Gene pool is the total genetic variation present in a population. It includes all genes and all alleles across individuals, and the frequencies of those alleles. This reservoir of variation provides the material that evolution acts on through mutation, recombination, gene flow, genetic drift, and natural selection, shaping how populations adapt over time. Autotrophs describe organisms that make their own food, which is about nutrition, not genetic variation. Comparative embryology studies developmental similarities across species to infer relationships, not the amount of variation in a population. Descent with modification is the broad idea of how evolution occurs, not a measure of current genetic diversity. So the term that best describes the total genetic variation present in a population is gene pool.
