Evolution Unit Study Guide (Ch.1-Ch.14) PDF

Summary

This document is a study guide for an evolution unit. It includes multiple-choice and short-answer questions about topics such as mutations, variations, heredity, Darwin's and Lamarck's theories, natural and artificial selection, and more. A section of the document refers to an evolutionary tree.

Evolution Unit Study Guide (Ch.1-Ch.14) 1. What is the definition of mutation? Give an example. 2. What is the definition of variation? Give an example. 3. What is the definition of heredity? Give an example. 4. What is the difference between Charles Darwin’s Theory and Jean Baptiste Lamarck’s Theory? 5. How does something become resistant, like bacteria to antibiotics? 6. What is natural selection? 7. What is artificial selection? 8. What is the difference between acquired traits and heritable traits? 9. Describe the sickle cell mutation including its pros and cons. 10. What would be the genotype of Sickle Disease for a person who is Homozygous recessive (use the letter S). 11. What is the difference between phenotype and genotype? 12. What is the difference between homozygous and heterozygous? 13. When is an organism considered a new species? For questions #10-12 refer to the following paragraph: A population of dolphins eats the silver fish that live near the coral reefs. Every so often, the silver fish have colorful offspring. The silver offspring are usually seen more quickly by the dolphins and eaten sooner. 14. What would happen to the colorful fish if the coral reef started to lose its color and die? 15. The dolphins eat both fish, colorful and silver, but what would happen to the colorful fish population compared to the silver fish population if the dolphin population can see the silver fish better? 16. Why is this change of color occurring in the fish population? Refer to the evolutionary tree below to answer questions #17-19: 17. Which species evolved the longest ago? 18. The perch is most closely related to which species? 19. Who is the ancestral species to the pigeon and the rat? 20. True or False. There are more insect species than mammal species? 21. List the organisms from oldest to youngest: Fish, mammals, bacteria 22. What is the difference between a fossil being found on the bottom layer of rock versus being found on the top layer of rock? 23. How did land mammals evolve into whales? 24. What is the sixth extinction? 25. What is the correlation between evolution and humans? How have humans changed evolution in our world today? How are humans affected by evolution? 26. Is bacteria multicellular or unicellular? For questions 26-29, refer to the paragraph and punnett square below: In dogs, the gene for long hair is the dominant allele (H) and the recessive allele for short hair is (h). 27. Each box in the punnett square box is equal to what percentage? 28. Parent #1 has a genotype Hh and Parent #2 has a genotype HH. What is the probability that the offspring will have long hair? 29. What are the chances of the offspring being homozygous recessive? 30. Parent #2 has a genotype of _________ and a phenotype of __________.
