Question 5 [HINT: This problem wants you to calculate gene number from the proportion of individuals in the extreme classes, not from the number of phenotypes.] A farmer has two pure-breeding varieties of tomatoes: Little Pete (average fruit diameter 2cm) and Big Boy (average fruit diameter 14 cm). The farmer crosses Little Pete and Big Boy and obtains F1 plants with fruit averaging 8cm in diameter. When he intercrosses the F1s to obtain F2s, he examines 2000 F2 plants and finds two plants that produce fruit even smaller than Little Pete and three plants that produce fruit even larger than Big Boy. From these data, how many genes can we infer are involved in controlling fruit size in these plants? What is the genotype of Little Pete? What is the genotype of Big Boy? What is the genotype of the F1s? What are the genotypes that are bigger than Big Boy? What are the genotypes that are smaller than Little Pete?

QUESTION 6 Assume that a researcher is studying coat color in voles. Three strains of white vole have been isolated: milky, blanc, and weiss. White is a recessive trait in each strain. Homozygous white voles are obtained for each strain. Consider the following crosses: milky X weiss = all white progeny (mutant) milky X blanc = all brown (wild-type vole color) blanc X weiss = all brown (wild-type vole color) The conclusion most consistent with these results is O A all three strains have mutations in the same gene. O B. all three strains have mutations in different genes. OC. milky and blanc have mutations on the same gene, weiss has a mutation in a different gene. D. milky and weiss have mutations on the same gene, blanc has a mutation in a different gene. O E. weiss and blanc have mutations on the same gene, milky has a mutation in a different gene.

Complete the problem below and upload your work here. Partial credit will be considered. In corn, purple kernels (P) are dominant over yellow kernels (p) and round kernels (R) are dominant to wrinkled kernels (r). In a cross of PpRr (purple, round) with a pprr (yellow, wrinkled) plant, the following progeny were observed: Phenotype Observed Expected (O-E) (O-E)2/E Purple, Round 117 Yellow, Round 126 Purple, Wrinkled 130 Yellow, Wrinkled 127 Total=500 Fill out the expected values in the chart above and calculate the Chi-Square value for your table, look up the p value associated with the Chi-Square. How many degrees of freedom do you have in this cross? 2. What is your Chi Square value? 3. What is the p value for this cross and what does your value mean? Make sure to explain the p value clearly in a couple of sentences.
