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**.
In this case:
- The plant with the genotype RR has red flowers.
- The plant with the genotype WW has white flowers.
