lol I have no idea sorry

All of the produced flowers would be Pp purple is the dominant form of the allele

The heterozygous plants are purple, therefore purple is the dominant allele. 

Assuming it is a single gene with only two possible alleles and the other colour is white; a cross between two heterozygous plants (Pp X Pp) should produce 3 purple and 1 white offspring. This means 3/4 will be purple. 

1 offspring will have the genotype PP (purple), 2 will have Pp (purple) and 1 will have pp (white).
