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

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 .

Answer 1

Correct conclusion: If a plant has white flowers, then its genotype must be pp (homozygous recessive).

Explanation: Purple (P) is dominant, so purple plants can be PP or Pp. White appears only when the recessive allele is homozygous (pp).
