In garden peas, tall (T) is dominant to short (t), Purple Flowers are (P) dominant to white flowers (p), Axial flowers (A) are dominant to terminal flowers (a), and yellow seeds (G) are dominant to green seeds (g). An individual from a true breeding line of tall, purple flowered, axial-flowered, yellow seeded pea plants is mated to an individual from a true breeding line of short, white flowered, terminal-flowered, green-seeded plants. The F1 are allowed to self-fertilize and produce an F2. What proportion of the F2 is expected to exhibit purple flowers and yellow seeds?
