Incomplete dominance is an exception to Mendel's rules where neither allele is completely dominant over the other, resulting in a blending of the traits from both parents. For example, in snapdragons, the red and white flower color alleles exhibit incomplete dominance, resulting in pink flowers when a plant with a red-flower allele is crossed with a plant with a white-flower allele.
