Answer:
D. About half of the offspring will have purple flowers, and about half of the offspring will have white flowers.
Step-by-step explanation:
Purple flower is dominant over white flower, therefore a cross between Pw and ww will produce four offsprings, fifty percent of which will have purple flowers and the other fifty percent will have white flowers. The genotypes of the offsprings are Pw and ww. Pw will manifest outwardly as purple flowers while ww will manifest outwardly as white flowers.
