Another trait in pea plants that follows a simple inheritance pattern is flower colour. Purple flowers are a dominant trait while white flowers are a recessive trait.

Explain what this difference means in terms of the alleles for flower colour.

Purple flowers are a dominant trait, so a pea plant only needs one allele for purple flowers in order to have the trait. White flowers are a recessive trait, so a pea plant needs two alleles for white flowers in order to have the trait. If a plant has both a dominant allele and a recessive allele then the dominant trait of purple flowers will be expressed.

When a trait has two separate gene-level versions, there are dominant and recessive traits. The trait that emerges initially or is most obviously displayed in the organism is its dominant trait. Recessive traits are those that are present in the organism but are not visible at the gene level.

  • The allele that results in a purple flower must be dominant (PP) if a purple and a white flower are crossed and the majority of the offspring are purple.
  • As a result, only the offspring who contain both alleles for white will truly be white (pp).
  • An example of this would be a purple flower, which may have an allele for  white but would be purple due to presence of a purple allele (Pp). this type of individual will be heterozygous dominant.
  • The characteristics of an offspring can be easily determined using dominant and recessive alleles.
