14. In what sense does the Hardy-Weinberg principle act as a null hypothesis? a. It is the starting point of all evolutionary studies. b. It specifies the conditions that need to be controlled in an evolutionary study. c. It specifies what genotype frequencies should be, given measured allele frequencies. d. It specifies what should be observed if no evolution is currently occurring at a particular gene.

PRACTISE QUESTIONS BIOL 1001 W2012 Key 17. Some biologists encapsulate evolution by natural selection with the phrase “mutation proposes, selection disposes”. Explain what they mean, using the formal terms you have learned to describe evolutionary processes. 18. Of all the mutations that occur in a population, why do only a small fraction become widespread among the population’s members? 19. In 1986 a nuclear power accident in Chernobyl, USSR (now Ukraine) led to high radiation levels for miles surrounding the plant. The high levels of radiation caused elevated mutation rates in the surviving organisms, and evolutionary biologists have been studying rodent populations in the Chernobyl area ever since. Based on your understanding of evolutionary mechanisms, which of the following most likely occurred in the rodent populations following the accident?
20. Why are mutations important in evolution, when most mutations are harmful?
21. Natural selection can only act on traits:
