Solution-What phenotypicratio do you expect for the f2 | Homework Helpers

1. Suppose a particular house plant can have either green leaves or yellow leaves, and that itsflowers can be either purple or white. A true-breeding purple flowered green leaf plant iscrossed with a true-breeding white flowered yellow leaf plant. The F1 plants are selfed toproduce the following F2 plants:green leaves, purple flowers: 190green leaves, white flowers: 60yellow leaves, purple flowers: 50yellow leaves, white flowers: 20

a. For each of the two traits, which allele is dominant and which is recessive?

b. If leaf color and flower color are inherited as independently assorting genes, what phenotypicratio do you expect for the F2 generation?

c. Do the observed F2 results fit the hypothesis you have proposed in part b?
