Post by: Andrearcarter95 on Mar 29, 2018
In a certain variety of plants, a cross between a red-flowered plant and a white-flowered plant
  produced an all-red flower F1. In the F2 there were 140 red-flowered plants, 50 cream-flowered plants,
  and 65 white-flowered plants.
  (a) Offer an explanation for this F2 ratio.
  (b) What ratio would be produced in a testcross of the F1 hybrid?
  (c) What ratio would be produced if all the white-flowered F2 plants were crossed among
  themselves? What will be an ideal response?
 
 

Question 2

In sweet peas, genes C and P are necessary for colored flowers. In the absence of either (__ pp or
  cc __), or both (cc pp), the flowers are white. Give the probable genotype of a plant with colored
  flowers and a plant with white flowers that produced 38 plants with colored flowers and 42 plants with
  white flowers. What will be an ideal response?
