The terms dominant and recessive are used in the inheritance pattern of traits in genetics. Dominant traits mask the expression of the recessive alleles while the recessive traits can only be expressed when two copies of the allele is present.
The genotype of the purple (phenotype) flower is PP and that of the white flower (phenotype) is pp
- Phenotypes can be regarded as the outward appearance of the trait expressed.
- Since the purple flowers are dominant over the recessive their genotype would be PP or Pp (their phenotype is purple).
- While the white flowers phenotype would be white and genotype pp as they are recessive.
