Answer 1

The correct conclusion based on the information provided is:

If a plant has white flowers, then its genotype must be pp.

This is because the only way to express the white flower phenotype is to have two recessive alleles (pp). For purple flowers, the genotype can either be homozygous dominant (PP) or heterozygous (Pp), so we cannot conclude that the genotype must be Pp just because the flowers are purple.
