Two traits are simultaneously examined in a cross of 2 pure-breeding pea plants varieties. 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 the traits pinched and yellow and a resulting F1 plant is self-crossed. A total of 640 F2 progency are phenotypically categorized as follows:
Swollen-yellow 320
Swollen-green 120
Pinched yellow 120
Pinched green 40
Questions:
a. What is the PR observed for pod shape? Seed color?
b. What is the PR observed for both traits consedered together?
c. What is the dominant relationship for pod shape? Seed color?
