In P plants the ALLELE for purple flowers P is dominant over the ALLELE for white flowers which conclusion about genotype and genotype is possible. Would it be if a plant has purple flowers then it's genotype must be PP or if a plant has white flowers, then it's genotype must be PP or if a plant has purple flowers, then it's genotype must be PP or if a plant has white flowers, then it's genotype must be PP.
If a plant has purple flowers, then it's genotype must be PP. This conclusion can be drawn because the allele for purple flowers (P) is dominant over the allele for white flowers. Therefore, if a plant displays the dominant trait (purple flowers), it must have two copies of the dominant allele (PP) in its genotype.
