Incomplete dominance is a genetic situation in which one allele does not completely dominate another allele, resulting in a blending of traits. This means that when an organism has two different alleles for a trait, the phenotype expressed is a mix of the dominant and recessive traits rather than just displaying the dominant trait.
For example, consider the case of flower color in snapdragons. If we have a red flower (RR) and a white flower (rr), when they are crossed, the resulting offspring (Rr) will have pink flowers. Instead of one color completely overshadowing the other, the traits blend together to create a new phenotype. This phenomenon illustrates how incomplete dominance can lead to a variety of expressed traits in offspring, showing the beauty and complexity of genetic interactions.
