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)

Question

Responses

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 white flowers, then its genotype must be Pp.

Answer 1

The correct conclusion is:

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

This is because the white flower phenotype is expressed only when the genotype is homozygous recessive (pp), as the dominant allele (P) masks the recessive allele (p).
