Datura stramonium (the Jimsonweed) expresses flower colors of purple and white and pod textures of smooth and spiny. The results of two crosses in which the parents were not necessarily true breeding are shown at the top of the next column.
(a) Based on these results, put forward a hypothesis for the inheritance of the purple/white and smooth/spiny traits.
(b) Assuming that true-breeding strains of all combinations of traits are available, what single cross could you execute and carry to an F 2 generation that will prove or disprove your hypothesis? Assuming your hypothesis is correct, what results of this cross will support it?
