In pea plants, the allele for purple flowers, P, is dominant over the allele for white flowers, p. What conclusion about phenotype and genotype is possible?

Answer 1

If the allele for purple flowers, P, is dominant over the allele for white flowers, p, three possible conclusions about phenotype and genotype can be made:

1. Individuals with the genotype PP or Pp will have purple flowers as their phenotype.
2. Only individuals with the genotype pp will have white flowers as their phenotype.
3. Individuals with the genotype Pp will have purple flowers as their phenotype since the dominant allele P overrides the recessive allele p.
