Detailed explanation-1: -The pink flower color trait, which is an example of incomplete dominance, occurs in nature, such as those found in pink-flower-bearing angiosperms. Turns out the dominant allele is not expressed “completely” as shown in Figures 1 and 2 – incomplete dominance (Punnett square).

Detailed explanation-2: -Incomplete dominance is when the phenotypes of the two parents blend together to create a new phenotype for their offspring. An example is a white flower and a red flower producing pink flowers. Codominance is when the two parent phenotypes are expressed together in the offspring.

Detailed explanation-3: -The best example of codominance is ABO blood group. ABO blood grouping is controlled by gene I which has three alleles A, B, and O and show codominance.

Detailed explanation-4: -This type of allelic relationship was termed codominance. It appears as if the red and white alleles are interacting in the heterozygote to generate the pink flowers. Another example of codominance can be seen by looking at a biochemical phenotype.
