BIO 340 Activity # 5: Hardy-Weinberg and Chi-square analysis (PAGE 1 of 2) Name (Last, First): The following data was obtained from a previous BIO 340 class. Data obtained from reference papers regarding the USA population are also provided and will be used to determine the "Expected" frequency and counts. You will have to analyze the data and provide phenotype, genotype and allele frequencies as well as perform a chi-square analysis. Complete every single empty square. For frequencies, (O-E)²/E and X² round to two decimal places. For counts use whole numbers.

Write down your answer next to each of the compounds. Sodium benzoate H₁- Phenyilthiocarbamide (PTC) Ho Thiourea Ho How do the BIO 340 results compare to those of previously published data from the USA population? Note: Compare the genotype/allele frequencies of each of the test papers. Did you expect these results? Explain why. Mention 3 reasons why most populations are NOT in Hardy-Weinberg equilibrium: 1. 2. 3 Total 1 1
