Question

Scientists performed an experiment with pea plants, set up much the same way as Mendel's pea plant genetic experiments. The scientists studies two traits simultaneously, flower color (purple or red) and pollen shape (long or round). They started with true breeding purple and long plants and crossed them with true breeding red/round plants. The resulting F1 plants all demonstrated purple flowers and long pollen. The F1 plants were the crossed with each other. The expected and observed results are shown here. What relevant question is appropriate to ask next based on conclusions drawn from the observed data?

Answer 1

Are the genes for flower color and pollen shape located on the same chromosome, preventing an independent assortment of these genes?

Explanation: When genes are linked on the same chromosome, they tend to move together during mitosis, unless they are randomly separated during crossing over. In this case, the number of long, purple plants and red, round plants is larger than expected, so gene linkage must be playing a role.

Answer 2
