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: -Incomplete dominance can occur because neither of the two alleles is fully dominant over the other, or because the dominant allele does not fully dominate the recessive allele. This results in a phenotype that is different from both the dominant and recessive alleles, and appears to be a mixture of both.

Detailed explanation-3: -Incomplete dominance results in heterozygotes with intermediate phenotypes, as in the case of snapdragons when parents with red flowers and white flowers are crossed resulting in heterozygous offspring with pink flowers.

Detailed explanation-4: -Answer and Explanation: Incomplete dominance is expressed in a phenotype as a combination of both alleles. For example, if a flower has the allele for red petals and the allele for white petals and it has incomplete dominance, the flower will have a phenotype of pink petals.
