Detailed explanation-1: -Incomplete dominance (biology definition): a lack of dominance in either of two different alleles in heterozygotes, so that the phenotype is intermediate between that of homozygotes for either of the two alleles.

Detailed explanation-2: -This type of relationship between alleles, with a heterozygote phenotype intermediate between the two homozygote phenotypes, is called incomplete dominance.

Detailed explanation-3: -In codominance, neither allele is dominant over the other, so both will be expressed equally in the heterozygote. In incomplete dominance, there is an intermediate heterozygote (such as a pink flower when the parents’ phenotypes are red and white).

Detailed explanation-4: -Incomplete dominance occurs when the phenotype of a heterozygote offspring is somewhere in between the phenotypes of both homozygous parents; a completely dominant allele does not occur.

Detailed explanation-5: -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.
