Mitchell and Emma are senior students that share a biology class. Their high school has a section on school property that has been used to grow various plants over the years. Each student is required to select a plant to study for their final project. The pictures show some of the plants that are grown on school property. The tulips, irises, and daffodils reproduce asexually. The snapdragons and the roses reproduce sexually.



Mitchell is interested in the snapdragons that reproduce sexually. He knows that purple (P) is dominant to white (w). Mitchell crosses a homozygous purple plant with a homozygous white plant. If he breeds two of the first generation offspring together, what percentage of the second generation offspring can Mitchell predict will most likely be white?

a. 25%
b. 50%
c. 75%
d. 100%
