Question

Imagine that you are interested in developing a new tomato plant that will include the large size and sweetness from one parent and yellow color from another parent. The first parent plant has bland-tasting small yellow tomatoes and the other parent has sweet-tasting large red tomatoes.
The chromosomes and alleles of the two plants are shown below.
Plant #1: Bland (B), Small (1), Yellow (1)
Plant #2: Sweet (b), Large (L.), Red (R)
Think about what you learned about inheriting traits from the lab to answer these questions.
1. Explain (in sentence form) why it is or is not possible for any of the offspring of these parents to have the sweet gene expressed in its phenotype. To illustrate your explanation,  you may use a diagram or use the Punnett squares below to show the genotypes of the possible offspring. Include a percent chance in your answer.
2. Explain whether or not it is possible to create a tomato plant with sweet, large, yellow tomatoes from a cross of Plant #1 and Plant #2.
3. After years of disappointment, you find one plant out of thousands in your greenhouse that is producing large yellow tomatoes! How might this have happened?
