Instructions - genotype number questions

 When the genotype number type of question comes up, you'll be given the number of each genotype and use that information to calculate what is the expected number of individuals in one of the genotypes if the Hardy-Weinberg equation is correct (which genotype you are asked for is selected randomly). See the introduction section of this website to see how to perform those calculations. The multiple-choice question displays the number to one decimal places, so there may be some variation in your numbers if you used more or fewer. However, the results should be close enough to pick the correct choice. Also note, the answers are in random order, so you should check all the answers because it is possible to have more than one answer that is close to the correct one. For this type of question there will always be five options. If there are multiple options with the same value, you can choose any one of them - if it is the correct answer, you will receive credit regardless of which one you selected. For the fill-in question you should enter the number to one decimal place to minimize the difference between your answer and the one calculated by the app.
