Genetic Factors in Inheritance Quick Check 3 of 53 of 5 Items Question Consider that a plant with genotype RR has red flowers and a plant with genotype WW has white flowers.

In incomplete dominance, when two homozygous plants with different traits are crossed, the resulting offspring exhibit a blend of those traits.

In this case:

  • The plant with the genotype RR has red flowers.
  • The plant with the genotype WW has white flowers.

When these two plants are crossed (RR x WW), all the offspring will have the genotype RW, which expresses a blended phenotype due to incomplete dominance.

Therefore, the offspring of the cross would be all pink.
