(3rd ed.) Page 1 BIO 100 LAB SIGN OFF PAGE - UNIT 11 Name ___________________________ Please staple all of your lab pages for this Unit together with this page as the top. You will use this page to get your Labs for Unit 11 signed off by the Biology Learning Center staff. You need to have all of the following steps initialed by a staff member before you will be allowed to take the Unit 11 Exam. After you have obtained all of your sign offs for this Unit, be sure that a BLC staff member indicates on your Lab Card that you are OK to take the Unit 11 Exam. Also, keep this sign off page, along with your completed lab worksheets, as proof of your lab completion. If your Lab Card indicates that you have not completed the required Labs for this Unit, and you feel that you have, it is up to you to provide proof that you have indeed done the Labs. Keep this page! ___________ Unit 11, Step 2A (Hardy-Weinberg practice questions #1-5) ___________ Unit 11, Step 2B (Population Genetics problem I) ___________ Unit 11, Step 2C (Population Genetics problem II) *BLC Staff: After the student receives his/her last initial on this page, please record that he/she has completed the required lab signoffs for this unit.Page 2 of 4 NOTE: DO NOT ATTEMPT ANY OF THESE LABS UNTIL AFTER YOU HAVE READ THE TEXTBOOK CHAPTER AND VIEWED THE CORRESPONDING STUDY GUIDE! THEY PROVIDE THE NECESSARY BACKGROUND INFORMATION. Unit 11, STEP 2A: Hardy-Weinberg Practice Questions This lab can be done at home. Start by going to the Biology 100 website and clicking on the link to the Hardy-Weinberg Population Genetics tutorial under Steps 2A-C. After you have viewed the tutorial, answer the following questions and solve the two population genetics problems. YOU MUST SHOW YOUR WORK FOR THE PROBLEMS! After you have completed each part of the activity, take your worksheets to the front desk in the Biology Learning Center for a sign off. We will begin by answering a few questions about Hardy-Weinberg. Circle the correct answers for each of the statements below : 1. In the equation p + q = 1, p stands for the frequency of ( dominant / recessive ) alleles. 2. In the equation p + q = 1, q stands for the frequency of ( dominant / recessive ) alleles. 3. In the equation p2 + 2pq + q2 = 1, p2 stands for the frequency of ( homozyous dominant (AA) / heterozygous (Aa) / homozygous recessive (aa) ) genotypes. 4. In the equation p2 + 2pq + q2 = 1, 2pq stands for the frequency of ( homozyous dominant (AA) / heterozygous (Aa) / homozygous recessive (aa) ) genotypes. 5. In the equation p2 + 2pq + q2 = 1, q2 stands for the frequency of ( homozyous dominant (AA) / heterozygous (Aa) / homozygous recessive (aa) ) genotypes. After you have completed these questions, take your worksheets to the front desk in the Biology Learning Center for your lab sign off. (Bio 100, Unit 11, Step 2A)(3rd ed.) Page 3 Unit 11, STEP 2B - PROBLEM I: In a population of moths, 19% have orange spots on their wings. The “A” allele for orange spots is dominant over the “a” allele for yellow spots. What are the allele frequencies, genotype frequencies, and phenotype frequencies in this population of moths? Allele frequencies: Genotype frequencies: Phenotype frequencies: A = AA = orange spots = a = Aa = yellow spots = aa = After you have completed this problem, take your worksheets to the front desk in the Biology Learning Center for your lab sign off. (Bio 100, Unit 11, Step 2B)Page 4 of 4 Unit 11, STEP 2C - PROBLEM II: In a population of beetles, 75% have green legs. The “G” allele for green legs is dominant over the “g” allele for blue legs. What are the allele frequencies, genotype frequencies, and phenotype frequencies in this population of beetles? Allele frequencies: Genotype frequencies: Phenotype frequencies: G = GG = green legs = g = Gg = blue legs = gg = After you have completed this problem, take your worksheets to the front desk in the Biology Learning Center for your lab sign off.
