Anthony GambinoAmanda ChristopherBiological Anthropology9/15/17Lab 4 (Exercises 1-5)Exercise 1Work in a small group or alone to complete this exercise. In Lab 2, Exercise 7, you determinedthe amino acid sequence for the following strand of DNa:That strand has mutated. It is now:Use your knowledge of mutation and protein synthesis to answer these questions:1.What mutation has occurred?
2.Will this mutation have a real effect? Why or why not? (Hint: You may want to tryExercise 8 from Lab 2 again, using the mutated DNA strand to make the mutatedprotein.)
Exercise 3Work in a small group to complete this exercise. You have a cup of beans in front of you with 20white beans and 20 red beans. These beans represent the alleles for a simple Mendelian trait,where red is dominant (R) and white is recessive (r). The cup holds the alleles for an entirepopulation (the gene pool).Step 1:

Create a population from the gene pool. Randomly pull out pairs of two beans, and lay them outin front of you. Each pair of beans represents one individual’s genotype for this trait. You shouldhave a total of 20 pairs of beans (20 individuals in the population). Record the genotypes of theindividuals (pairs of beans) in the first table.IndividualGenotypeIndividualGenotype1Rr11Rr2RR12Rr3RR13rr4Rr14RR5Rr15Rr6RR16Rr7Rr17Rr8rr18rr9Rr19rr10Rr20Rr1.How many recessive alleles are present in your overall population?
