Which statement is most correct about the relation between heredity and evolution?
Answer and explanation
Correct answer: Variation and heredity together provide the basis of evolution
Heredity transmits genetic information and traits from parents to offspring, whereas variation creates differences among offspring. Evolution requires both: variation provides alternative traits, and heredity preserves and passes advantageous heritable traits to later generations. Natural selection can therefore change the frequency of traits in a population. Heredity alone would copy traits, and acquired traits alone do not adequately explain genetic evolution.
