BioEE278 Spring 2008 Zamudio Practice Questions, Prelim 1 These are practice questions for Prelim Exam 1 (Feb 28, 2008). These questions are representative of the kind of question you can expect on the exam. We will also post a key to these questions, so you can check your answers. However, the best strategy for study is not to just look at the key! Try to complete this practice exam as if it were real. That will help you gauge the areas you need to study more. 1. Briefly list the attribute(s) of a theoretical population that would have an average inbreeding coefficient of exactly zero (hint: this can best be answered with under 10 words). 2. You are studying a toad species that lives only in tiny vernal pools (ponds that fill in the rainy season but dry out in the dry season) at highly scattered locations across the deserts of Arizona. You sample 20 toad tadpoles from each of 10 ponds, and sequence from each a stretch of coding DNA. You discover three alleles that differ only at synonymous nucleotide sites. You then find that the genotype frequencies in the samples from each pond are VERY different from the proportions expected under Hardy-Weinberg equilibrium, but also that these frequencies differ strikingly among the 10 ponds sampled. Start by listing the five HW assumptions below. All five assumptions are likely violated in these toad populations, but of the five possibilities, which in this case are likely to contribute most to your observed deviation from HW equilibrium (and why)? Which are likely to be relatively unimportant (and why)? For each assumption, circle either ‘violation important’ or ‘not important’ and in the space below provide a sentence to justify your rationale. 1. violation important not important Why? 2. violation important not important Why? 3. violation important not important Why? 4. violation important not important Why? 5. violation important not important Why? 3.
