The F1 plants were crossed to each other (self-cross) and the following F2 plants were observed: 95 white beet plants, 25 red beet plants and 7 yellow beet plants. How many genes determine beet color? Give the genotype of the parental white beet plant and the yellow beet plant. (Use A for a single gene inheritance, A and B for two gene inheritance and A, B, C for three gene inheritance. Write the genotype using proper notation.) Genotype of P1 white beet plant: Genotype of P1 yellow beet plant: What phenotypic ratio is observed in the F2 progeny? (List the ratio as a complete fraction next to the phenotype).

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.
- 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 1 A testcross of AaBb gives 10% Aabb progeny.
