Answer:

The gardener performed hybrid crossing and the purple plant's genotype is: PP

Explanation:

  • Since we know the offspring's phenotype (appearance) is purple, the genotype can either be PP or Pp.
  • We know that the farmer crossed a white plant, we can denote it's genotype as pp and a purple plant with a dominant trait.
  • Because the farmer crossed the white plant with the purple plant, this tells us that the genotype of the purple plant must be PP.
