GPT-4o · Answer

The correct conclusion about phenotype and genotype is:

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

This is because white flowers are recessive, and hence, for a plant to have white flowers, it must have two recessive alleles (pp). Purple flowers can be either PP or Pp because the allele for purple flowers is dominant.
