Question

Hi, there are 2 parts of this question

S. superis is a rare flowering plant that can produce blooms in two colours, purple (P) and teal (p), and two shapes, four petals (F) and seven petals (f). Purple is dominant to teal, and four is dominant to seven petals. S. superis is a diploid organism, 2n = 4, that can both self-fertilize and mate with other plants of the same species (out-cross). You find one of these rare plants in your garden and it has purple flowers with four petals. Assuming this lonely plant must self-fertilize what potential offspring phenotypes could you see?

Select one:

a. Purple with seven petals

b. Purple with four petals

c. Teal with seven petals

d. All of the phenotypes listed are possible depending on the genotype of the plant.

Your friend is working with S. superis plants in the lab and has set up a cross between a plant with four purple petals and a plant with seven teal petals. Of the 200 offspring from the cross all have purple petals but about 1/2 have four petals and 1/2 have seven petals.

If you were to write out the cross that your friend set up what would it look like genotypically?

Select one:

a. PPFf X ppff

b. PpFf X PpFf

c. PpFF X ppff

d. PpFf X ppff

e. PPFF X ppff
