What does the Law of Incomplete Dominance describe?

The Law of Incomplete Dominance describes a genetic situation where two alleles combine to produce a phenotype that is distinct from the phenotypes of individuals with either allele alone. In this case, neither allele is completely dominant over the other, leading to a blending of traits. For example, if one parent has red flowers and another has white flowers, the offspring may have pink flowers, demonstrating this blending effect.

This principle highlights the complexity of inheritance beyond the simple dominant-recessive relationships. Incomplete dominance allows for a variety of phenotypes to emerge in a population, enriching genetic diversity and providing a wider range of characteristics than those represented by complete dominance, where one allele would completely mask the presence of another.
