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

If a plant has purple flowers, then its genotype must be Pp.
If a plant has purple flowers, then its genotype must be Pp .

If a plant has purple flowers, then its genotype must be PP.
If a plant has purple flowers, then its genotype must be PP .

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

Answer 1

The correct conclusion is:

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

This is because the only way for a plant to express the white flower phenotype (which is recessive) is for it to have two recessive alleles (pp). If the genotype were Pp or PP, the phenotype would be purple flowers.
