Question

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 small p small p .

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

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

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

Answer 1

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

Explanation: White is recessive, so the white phenotype only appears when the plant is homozygous recessive (pp). Purple plants can be either PP or Pp.
