Bio 100 Exam 3 (Jaeger U NLV) Questions and Answers 100% Pass **Evolution is defined as** ✔✔ any change in the phenotype of a population over successive generations due to genetic factors. **Common Descent with Modification entails** ✔✔ species undergoing modificati ons across generations. These changes can lead to the emergence of new, distinct species. **Species are** ✔✔ various types of organisms. Individuals within the same species share genetic similarities and can potentially interbreed . **A population consist s of** ✔✔ all individuals of the same species inhabiting a specific area at a given time. **Fitness is defined as** ✔✔ the success of reproduction, which involves leaving behind offspring. **Natural selection acts as** ✔✔ an agent of evolution, where tra its conferring reproductive advantages spread through a population over generations. **Biotic potential indicates** ✔✔ that most populations can produce more offspring than the environment can support. **Heritable traits are those that can be** ✔✔ passed on to the next generation. **Over time,** ✔✔ advantageous traits spread throughout the population. **Competition within natural selection ensures that** ✔✔ genetic traits providing advantages spread wi thin a population, while disadvantageous ones diminish. **What undergoes evolution?** ✔✔ Populations evolve. **Evolution of acquired characters suggests that** ✔✔ over time, an organism can accumulate enough changes that one species may diverge into two. This branching extends back through ancestral species. **The five agents of evolution include** ✔✔ natural selection, sexual selection, gene flow, genetic drift, and mutation. **Mutation involves** ✔✔ a change in DNA sequence. **Mutation serves as** ✔✔ the mechanism generating new genetic information. While most mutations are neutral or harmful, a few can benefit an organism's fitness. **Beneficial mutations are** ✔✔ the foundation of evolutionary change. **Whose theory proposed "Shorter Neck Giraffes Dying" as an illustration?** ✔✔ Darwin's Theory **Gene flow refers to** ✔✔ the movement of alleles between populations through migration. **Gene flow introduces** ✔✔ 'novel' alleles into a population from other populations. **Genetic drift involves** ✔✔ random changes in allele frequencies within a population.
