In a biological experiment a large quantity of plants were grown. For each plant the stem length was classified as being either tall or dwarf, and the position of the flowers was classified as being either axial or terminal. All together there were 412 tall axial plants. 121 tall terminal plants. 148 dwarf axial plants, and 46 dwarf terminal plants. According to the proposed genetic theory, the probabilities of the plants displaying each of these four characteristics should have relative magnitudes of 9:3:3:1, respectively. Is the data set consistent with the proposed genetic theory?
