Question 2 2. Comparative anatomy is useful for all but which of the following?

Question 3 3. Our modern corn was created through artificial selection from the ancestral plant _____.

Question 4 4.

Which of the following is an example of analogous structures or traits?

I. Leg bones of a human and leg bones of a penguin

II. Wing of a penguin and wing of a mosquito

III. Beak of a penguin and beak of a duck

Question 5 5. One way to overcome behavioral isolation that prevents animals from reproducing might be to _____.

Question 6 6. A population of lizards is split by an earthquake which leaves half of the population on an island and the other half on the tip of the peninsula. These lizards can't swim. What type of speciation will occur?

Question 7 7. What are homologous genes?

Question 8 8. A new mutation allows a cheetah to run faster and hunt down more prey than its slower counterparts. This mutation increased the _____ of the cheetah.

Question 9 9. Which best describes the general rate of evolution?

Question 10 10. Genetic variability describes which of the following?

Question 11 11. Which field would best describe why penguins and polar bears are not found in the same regions of Earth?

Question 12 12. Why do scientists use the Hardy-Weinberg equation?

Question 13 13. Two species of plants that do not cross-pollinate are an example of _____ isolation because they flower at different times of the year.

Question 14 14. Consider a population of fish where the length of a given fish's dorsal spine is determined by a single gene, which is defined by two different alleles. The dominant A allele encodes a long dorsal spine and the recessive a allele encodes a short dorsal spine. The fish is diploid and reproduces sexually. The number of AA individuals in this population is 500, the number of Aa individuals is 100, and the number of aa individuals is 400. If a new population was started with 10 AA, 20 Aa, and 10 aa fish, then what are the new allelic frequencies?

Question 15 15. The coat color gene of a population of squirrels is defined by a dominant allele G, which encodes a gray coat, and a recessive allele g, which encodes a black coat. In a population, genetic typing reveals the genotypic distribution to be 50 GG, 30 Gg, and 20 gg. If this population is in equilibrium, then what should the genotypic frequency of gg squirrels in this population be?

Question 16 16. Punctuated equilibria describes which phenomenon?

Question 17 17. Consider a population of fish where the length of a given fish's dorsal spine is determined by a single gene, which is defined by two different alleles. The dominant A allele encodes a long dorsal spine and the recessive a allele encodes a short dorsal spine. The fish is diploid and reproduces sexually. If the number of AA individuals is 500, the number of Aa individuals is 200, and the number of aa individuals is 300, then is this population in equilibrium? Why or why not?

Question 18 18. What is a genome?

Question 19 19. Which is true about random mutations?

Question 20 20.

Which of the following is an example of natural selection?

I. Albino animals are rare in nature because they are easy for predators to find.

II. The fastest gazelle is least likely to be eaten by a lion.

III. The gorilla that is strong enough to become alpha male is the most likely to pass on his genes.

Question 21 21. A scientist has observed animals in a particular habitat for some time. She notices that in a population of birds those with either short or long beaks can find more food than those with average sized beaks. Over time, she notices a higher proportion of birds in the population have either short or long beaks. She is observing:

Question 22 22. A scientist mates a blue population of lizards with a red population of lizards. She observes that one out of ten hybrid offspring survive to adulthood compared to, roughly, eight out of ten blue or red lizards. This is an example of _____.

Question 23 23. Which of the following is an example of convergent evolution?

Question 24 24. Which best describes genetic variation?

Question 25 25. Which is NOT true about the fossil record?

Page 6

Question 26 26. Some studies have shown that a single copy of the cystic fibrosis disease allele can confer resistance to tuberculosis to a person. This is an example of:

Question 27 27. After observing a population of fish with interesting protective spines, a scientist decides to move two of the fish into a new pond to create a new population of fish to study the ability of the fish to survive a new set of predators. Which of the following evolutionary agents did the scientist introduce?

Question 28 28. One species of sea urchin is able to mate with another, but fertilization is rarely successful. What is this an example of?

Question 29 29. Why is the peppered moth phenomenon uncommon?

Question 30 30. The coat color gene of a population of squirrels is defined by a dominant allele G, which encodes a gray coat, and a recessive allele g, which encodes a black coat. In a population, genetic typing reveals the genotypic distribution to be 50 GG, 30 Gg, and 20 gg. If this population is in equilibrium, then what should the genotypic frequency of Gg squirrels in this population be?
