Answer 1

The correct conclusion is:

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

This is because the allele for white flowers (p) is recessive, meaning that a plant must have two copies of the recessive allele (pp) to express the white flower phenotype. Alternatively, a plant can have one or two copies of the dominant allele (P), which would result in purple flowers (PP or Pp).
