Answer:
Incomplete dominance can be described as a phenomenon in which the dominant trait is not completely dominant over the recessive trait. Incomplete dominance can be determined when the dominant and the recessive trait merge to form a third type of trait. A new phenotype arises due to such a cross.
For example, when a black-feathered chicken is crossed with a white chicken and their alleles shown incomplete dominance, then offsprings having blue feathers can be seen.
