Detailed explanation-1: -Correct answer: A Punnet square reveals that 75% of the generation will be purple (PP or Pp) and 25% will be white (pp). Of the three purple flowers in the punnett square, two of them are heterozygous for color (Pp). The other flower is homozygous for the purple allele (PP).
Detailed explanation-2: -Hence, one can assign allele P for purple and p for white. Therefore, the flower with genotype Pp would produce violet color phenotype according to law of dominance.
Detailed explanation-3: -Thus, the allele associated with purple color is therefore said to be dominant to the allele that produces the white colour. The white allele, whose phenotype is masked by the purple allele in a heterozygote, is recessive to the purple allele.
