In pea plants, the allele for purple flowers, P, is dominant over the allele for white flowers, p. Which conclusion about phenotype and genotype is possible?(1 point) Responses 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.

The correct conclusion from the information given is:

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

This is because white flowers result from the presence of two recessive alleles (pp). The other statements do not accurately reflect the relationship between genotype and phenotype given that dominant traits can result from either homozygous dominant (PP) or heterozygous (Pp) alleles. Thus, a plant with purple flowers could have a genotype of either PP or Pp.
