Your friend has obtained some pea seeds from the Abbey of St.Thomas in Brno, where Gregor Mendel worked.He is very excited because not only did he obtain some yellow and green pea seeds from true-breeding plants (like the ones used in Mendel's famous experiment), he was also able to obtain some purple pea seeds from a true-breeding plant.First, your friend takes the true-breeding yellow and green pea seeds, repeats the cross that Gregor Mendel did, and obtains the same results: he sees 100% yellow-seeded pea plants in the F₁ generation, and 75% yellow-seeded pea plants and 25% green-seeded pea plants in the F₂ generation.His results are illustrated in Figure 19-30A.Your friend then decides to set up two more crosses.For cross #2, he crosses the true-breeding purple-seeded pea plants to the true-breeding yellow-seeded pea plants.The results from this cross are shown in Figure 19-30B.Next, for cross #3, he crosses the true-breeding purple-seeded pea plants to the true-breeding green-seeded pea plants.These results are shown in Figure 19-30C.

Figure 19-30
Given these results, if you were to take the purple-seeded pea plants produced in the F₁ generation in cross #2 and cross them to the purple-seeded pea plants produced in the F₁ generation of cross #3, what do you expect that the phenotype of the progeny would look like? Explain your answer.
