8) Suppose that red flower color (R-) is dominant to white flower color (rr) in Petunia. A friend has a petunia plant with red flowers and wants to determine whether the plant is RR or Rr. In order to determine the genotype, you cross it with a white-flowered petunia. (i) What is the name of the cross that you performed? (ii) How will this cross help you determine the genotype of the red flowered petunia? That is, how will the results from this cross differ if the red-flowered petunia is RR vs Rr?
