Detailed explanation-1: -Incomplete dominance occurs when neither trait is truly dominant over the other. This means that both traits can be expressed in the same regions, resulting a blending of two phenotypes. If a white and black dog produce a gray offspring, this is an example of incomplete dominance.

Detailed explanation-2: -An Andalusian chicken (found in Spain) is an example of incomplete dominance. An offspring produced shows incomplete dominance in its feathers as the parents (a white feathered male and a black feathered female chicken) breeds to produce an offspring with blue and tinged feathers.

Detailed explanation-3: -An example of codominance is the roan cow which has both red hairs and white hairs. In incomplete dominance a heterozygous individual blends the two traits. An example of incomplete dominance is the pink snapdragon, which receives a red allele and white allele.

Detailed explanation-4: -Incomplete dominance results from a cross in which each parental contribution is genetically unique and gives rise to progeny whose phenotype is intermediate. Incomplete dominance is also referred to as semi-dominance and partial dominance. Mendel described dominance but not incomplete dominance.
