Detailed explanation-1: -In codominance, neither allele is dominant over the other, so both will be expressed equally in the heterozygote.

Detailed explanation-2: -Codominance. Codominance occurs when both alleles are expressed equally in the phenotype of the heterozygote. The red and white flower in the figure has codominant alleles for red petals and white petals.

Detailed explanation-3: -Codominance Definition Codominance is a form of inheritance wherein the alleles of a gene pair in a heterozygote are fully expressed. As a result, the phenotype of the offspring is a combination of the phenotype of the parents. Thus, the trait is neither dominant nor recessive.

Detailed explanation-4: -These traits are called polygenic traits . The alleles of each gene have a minor additive effect on the phenotype. There are many possible combinations of alleles, especially if each gene has multiple alleles. Therefore, a whole continuum of phenotypes is possible. An example of a human polygenic trait is adult height.

Detailed explanation-5: -One allele is NOT always completely dominant over another allele. Sometimes an individual has a phenotype between the two parents because one allele is not dominant over another. This pattern of inheritance is called incomplete dominance.
