Unformatted text preview: n some flowers, a true-breeding, red-flowered strain gives all pink flowers when crossed with a white-flowered strain: RR (red) × rr (white) → Rr (pink). If flower position is inherited as it is in peas, what will be the ratios of genotypes and phenotypes of the generation resulting from the following cross: Axial-red (true breeding) × terminal-white? What will be the ratios in the F2 generation? 27. In sesame plants, the one-pod condition (P) is dominant to the three-pod condition (p), and normal leaf (L) is dominant to wrinkled leaf (l). These traits are inherited independently. Determine the genotypes for the two parents for all the possible matings producing the following offspring: a. 318 one-pod normal, 98 one-pod wrinkled b. 323 three-pod normal, 106 three-pod wrinkled c. 401 one-pod normal d. 150 one-pod normal, 147 one-pod wrinkled, 51 three-pod normal, 48 three-pod wrinkled e. 223 one-pod normal, 72 one-pod wrinkled, 76 three-pod normal, 27 three-pod wrinkled 28. Two traits are simultaneously examined in a cross of two pure-breeding pea-plant varieties...
