CODOMINANCE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following does NOT apply to incomplete dominance?
A
Alleles mix/blend in between both alleles
B
Both alleles show up equally in the offspring
C
Neither allele is dominant
D
A third phenotype is created
Explanation: 

Detailed explanation-1: -Incomplete dominance occurs because neither of the two alleles is completely dominant over the other. This results in a phenotype that is a combination of both. Gregor Mendel conducted experiments on pea plants.

Detailed explanation-2: -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-3: -Example: Incomplete dominance is seen in cross-pollination experiments between red and white snapdragon plants.

Detailed explanation-4: -Codominance occurs when both alleles are expressed equally in the phenotype of the heterozygote.
