Study Questions for all labs The intent of these questions is to help you study for the lab practical. For general study you will want to pay attention to the goals and objectives that are listed on the first page of each lab. If you can answer those questions well, you should do fine on this exam. You will need to make some basic calculations for the lab practical. Most formulas will be given to you (you will need to know how to calculate allele and genotype frequencies—no formulas will be give for those calculations). For any calculations you may be asked to do, you will need to understand why you are doing them and what the resultant values mean. It’s not enough just to plug in the numbers and get a result; that’s the most rudimentary level of knowledge. Instead, we want you to use those values to answer more sophisticated questions. That shows true understanding. Some questions on the lab practical will be the “you either know it or you don’t” types, but others will require a more in depth understanding, which leads to me to one quick note about learning: The most basic form of learning is to memorize and reproduce a bunch of facts. For example, being able to list the five conditions of Hardy-Weinberg equilibrium is easy to do. However, we do not want to stop there. Facts form the foundation for answering more sophisticated questions, and they are certainly important to know (if you don’t know anything, it’s impossible to even began answering questions about the world around us—Darwin, for instance, was very well-versed; without his knowing a great deal about the natural world, he would not have been able to develop his theory of evolution by natural selection). But can you use the facts you know? Can you use the conditions of Hardy-Weinberg to understand why a population might be evolving? Many exam questions assume you know the basics and want you to apply those basics to more sophisticated questions. We throw a few easy fact-based questions in to give you confidence, but what we are truly interested in is: “Can you use the information?” The lab practical will have a mixture of easy, fact-based questions and more sophisticated questions. For example, you might have to apply the ideas you learned to organisms you may never have seen before (natural selection applies to more than just mustard plants). Use your lab manual as a study guide as everything you need to know can be found therein. No answers are provided for the following questions, but a few hints are given on how to approach the more difficult ones. You may find some of the questions ask you the same thing but in different ways. I recognize this, but I do not think repetition is a bad thing. Again, you will not be asked to memorize formulas (these will be give in one form or another), but you should be able to use formulas to calculate a diversity index or population growth. Also, you should be able to calculate allele and genotype frequencies using the
