Question

individual work natural selection and evolution date: period: match the following terms with their corresponding definitions 1 natural selection a. a feature or behavior that helps an organism survive in its environment. 2 heritable trait b. selection in which traits that are specifically selected for by humans. 3 sexual selection c. a characteristic that is learned over the course of an animals lifetime. 4 adaptation d. shift in the inherited characteristics of a population over time 5 fitness e. a characteristic that is passed down through genes 6 acquired trait f. an organisms ability to survive and reproduce 7 artificial selection g. selection in which traits help the organism attract a mate 8 genetic variation h. selection in which traits are selected for by environmental factors 9 evolution i. each organism has its own unique set of heritable traits for questions 10 - 12, write the type of selection being displayed.

Explanation:

1. Natural Selection is the process where traits are selected by environmental factors, so 1 - H.
2. A heritable trait is passed down through genes, so 2 - E.
3. Sexual Selection involves traits that help an organism attract a mate, so 3 - G.
4. Adaptation is a feature or behavior that helps an organism survive in its environment, so 4 - A.
5. Fitness is an organism's ability to survive and reproduce, so 5 - F.
6. An acquired trait is learned over an animal's lifetime, so 6 - C.
7. Artificial Selection is selection in which traits are specifically selected for by humans, so 7 - B.
8. Genetic variation means each organism has its own unique set of heritable traits, so 8 - I.
9. Evolution is a shift in the inherited characteristics of a population over time, so 9 - D.

Answer:

1. H. Selection in which traits are selected for by environmental factors
2. E. A characteristic that is passed down through genes
3. G. Selection in which traits help the organism attract a mate
4. A. A feature or behavior that helps an organism survive in its environment
5. F. An organism's ability to survive and reproduce
6. C. A characteristic that is learned over the course of an animal's lifetime
7. B. Selection in which traits that are specifically selected for by humans
8. I. Each organism has its own unique set of heritable traits
9. D. Shift in the inherited characteristics of a population over time
