The pattern of inheritance known as incomplete dominance occurs when neither allele in a genotype completely masks the other, leading to a blended phenotype. In this type of inheritance, heterozygous offspring exhibit a phenotype that is a mix of both parental traits. A classic example is seen in snapdragon flowers, where crossing red and white flowers results in pink flowers. This contrasts with complete dominance, where one allele wholly overshadows the other. Incomplete dominance provides insights into genetic variation and the complexity of inheritance patterns.
