Codominance
In genetics, people inherit various physical properties, traits, and characteristics from their parents. This also includes various entities and organic beings like plants and animals. Various contexts, biotic factors, and themes like the biosphere, ecosystem, food chain, food web, symbiosis, and biome will also affect the proclivity of the said traits. Codominance is a phenomenon that occurs when the genes will produce a mixed result of the two traits.

What Is Codominance?
Codominance is a specific phenomenon when the child of two parents obtains traits that have both physical characteristics of each parent’s physical trait. For example, when a purple flower and a red flower are cross-bred, codominance might produce a flower with both purple and red flower petals.
How to Identify Codominance in a Punnett Square
The Punnett square is a tool people can use to determine the alleles that the parents will genetically pass on to their offspring. It can also determine the codominant trait that will be present in the whole equation.
Step 1: Create a Punnett Square
Begin by creating a Punnett square that will help you visualize the possible genotypes that the offspring will inherit. Not only that, but this will also provide you with a structure and a framework you can utilize to determine the codominance.
Step 2: List Down the Dominant and Recessive Traits
To use the Punnett square you must list down the dominant and recessive traits that the parents will pass on to their offspring. You will list the dominant and recessive traits on the X and Y axis respectively.
Step 3: Match the Alleles
Each trait will have a specific allele loadout that is specific to the trait. You must match the alleles in each quadrant in the table. You will end up with 4 different allele combinations in the Punnett square, which will be in the format of AA, Aa, or aa where the uppercase a is the dominant allele and the lowercase a is the recessive allele.
Step 4: Identify the Trait that is a Product of Two Different Alleles
The codominant trait is the trait with a dominant and a recessive allele in the punnett square, which is represented by the Aa combination. You must identify the presence of this allele formation in the Punnett square.
FAQs
Incomplete dominance is a phenomenon where the recessive trait or dominant trait is repressed, which will mean only the characteristic of the unsuppressed trait will be active. Codominance is a phenomenon where the offspring will receive a trait that is a combination of the recessive and dominant traits of a specific physical characteristic.Incomplete dominance vs. codominance; what is the difference between the two traits?
There are many observable examples of codominant traits naturally occurring in nature. For example, when a white chicken is paired with a gray rooster, their offspring can have a codominant trait wherein it will have a mix of gray and white feathers on its body.What are real-life examples of codominant traits?
The person’s eye color is a trait that has an incomplete dominance due to the characteristic’s ability to only manifest a recessive or a dominant gene. A trait can only be considered codominant if both dominant and recessive traits are present in the characteristics.Is a person’s eye color codominant or incomplete dominance?
Codominance is the phenomenon where a specific trait will manifest a blend of both physical characteristics of both dominant and recessive genes the parents have given to their offspring. It is important to know how to identify the possibility of a trait with codominance in their offspring.
