Unformatted text preview: . Pod shape can be either swollen or pinched. Seed color can be either green or yellow. A plant with the traits swollen, green is crossed with a plant with the traits pinched, yellow, and a resulting F1 plant is self-crossed. A total of 640 F2 progeny are phenotypically categorized as follows: Swollen, yellow 360 Swollen, green 120 Pinched, yellow 120 Pinched, green 40 a. What is the phenotypic ratio observed for pod shape? Seed color? b. What is the phenotypic ratio observed for both traits considered together? c. What is the dominance relationship for pod shape? Seed color? Genetics Problems/Knight2001 3 29. Consider the following cross in pea plants, where smooth seed shape is dominant to wrinkled and yellow seed color is dominant to green. A plant with smooth, yellow seeds is crossed to a plant with wrinkled, green seeds. The peas produced by the offspring are all smooth and yellow. What are the genotypes of the parents? What are the genotypes of the offspring? Basic Probabilities 30. A...
