Solution

The genotype of a plant with white flowers must be pp. This is because white flowers are recessive, and a recessive trait can only be expressed if both alleles are recessive (pp). If the plant had a genotype of PP or Pp, it would have purple flowers because the purple flower trait is dominant.
