Which statement gives the most correct relation between heredity and evolution?
Answer and explanation
Correct answer: Inherited changes accumulate over generations and guide evolution
Heredity transmits genetic information from parents to offspring, allowing particular variations to persist in a population. When heritable variations affect survival or reproduction, natural selection can change their frequency over many generations. This population-level, long-term change is evolution. Therefore option A correctly connects heredity with evolution. Acquired traits are not automatically inherited, heredity does not always prevent change, and evolution is not completed within the lifetime of one organism.
