- Which of the following is a form of a heritable trait that enhances an individual’s fitness? Adaptation Lineage FitnessWhich of the following would be the best measure of an organism’s evolutionary fitness? Lifespan Number of offspring Number of siblings Physical strengthAn organism’s relative fitness is measured by its ______. Group of answer choices Mutation rate Genetic variability Contribution to the gene pool of the next generation Health and stability in the face of environmental change
- Meaningful evolution occurs when __________. ○ a heritable trait affects survival and fitness ○ a heritable changed trait gives an organism a fitness advantage ○ a changed trait gives an organism a disadvantage ○ environmental factors changePhenotypic plasticity is the ability of an individual organism to express two or more genetically controlled phenotypes in response to environmental variation. Give an example and give some reasons why organisms depend on phenotypic plasticity instead of maintaining all their systems in a maximum sate of readiness at all times.Which of the following terms are used to apply ONLY TO SELECTION, and never to just evolution. Choose all that apply. Cost/benefit Selective advantage/disadvantage Founder effect Allele frequencies Fitness Bottleneck effect
- Which of the following is NOT a characteristic of determining whether a feature is an adaptation? Group of answer choices Reliability Genetic significance Efficiency EconomyWhich of these determines which adaptations in a population are best suited for survival? Group of answer choices: random chance members of the population the environment humansWhich statement is accurate about natural selection? It is a biological process that prevents species from adapting to significant changes in their environments. It is a biological process that leads a population to have a widespread expression of an advantageous trait. It is a biological process that allows a population to have a competitive advantage in many environments. It is a biological process that causes certain traits to be expressed less with each subsequent generation.
- Which one of these statements about fitness is most accurate? A. Fitness is a measure of strength & health B. Fitness may change at a population level, but is constant for an individual C. Fitness can only be measured at the population level D. Fitness is a measure of reproductive success E. Fitness is an overall measurement that applies to all evolutionary mechanismsWhich of the following best explains the phrase “survival of the fittest” in terms of evolution by natural selection? The strongest and fastest individuals will always survive and reproduce more often. The individuals that are the healthiest will always get more resources and survive better. Only individuals that have the most mates will survive with limited resources. The individuals that survive better and reproduce more often will pass their traits on more often.Natural selection is based on all of the following except individuals who survive longer tend to have more offspring than those who die young genetic variation exists within populations Individuals adapt to their environments and, thereby, evolve populations tend to produce more offspring than the environment can support the best adapted individuals tend to reproduce more
