A homozygousplant that has bitter fruit and yellow spots is crossed with ahomozygous plant that has sweet fruit and no spots. The F1 arecrossed to produce the F2.

  1. (a) What are the phenotypes with corresponding phenotypic ratiosof the F2?

  2. (b) If an F1 plant is backcrossed to thebitter, yellow-spotted parent, what phenotypes and

    proportions are expected in the offspring?

  3. (c) If an F1 plant is backcrossed to the sweet,non-spotted parent, what phenotypes and proportions

    are expected in the offspring?
