A dihybrid cross of two plants is done and the seed pod shape is examined. The seed stock was pure, both always made triangular pods. The pod shape is known to be controlled by two independently assorting genes. You cross the plants and produce an F1 generation and all the seed pods are triangular. Then you cross the F1 plants to each other in three independent experiments and the F2 data is presented in Table 1. Explain the type of epistasis that is event in this data. Suggest a molecular mechanism that can explain this type of gene interaction.
