Biology 101: Evolution and Natural Selection Flashcards actual exam questions and correct answers verified 100% Q66 Define: Evolution A The change in frequency of a populations inherited traits over subsequent generations. Evolution only occurs within populations; individual organisms do not change genetically over time to adjust to their environment. 67 Q Define: Natural selection A The change in frequency of a trait within a population, based on the effect that trait has on reproductive success. Traits that allow an organism to produce more viable offspring are more likely to be passed on to future generations.68 Q What qualities are exhibited by an organism with high fitness? A Organisms with high fitness are those that successfully produce a relatively large number of offspring. In general, fitness refers to the likelihood that an animal will pass down its genetic material. On the AP Biology exam, remember that fitness is determined by reproductive success alone. A stronger, more physically capable animal that cannot reproduce is less fit than a weaker animal that can reproduce. 69 Q Members of a population who possess beneficial traits survive long enough to produce offspring, while members with harmful traits often die before reaching sexual maturity. Which evolutionary
