What is codominance in genetics?
Codominance, in genetics, phenomenon in which two alleles are expressed to an equal degree within an organism. As a result, traits associated with each allele are displayed simultaneously. Examples of codominance include AB blood type in humans and red and white flower petals in rhododendrons.

It is the most common example of codominance in MN blood groups of humans. A person’s MN blood type is determined by two alleles, M and N, of a particular gene. An LM allele has an M marker on the surface of the red blood cells (RBCs), while an LNallele has an N marker. Individuals homozygous for the M allele have M as the RBC antigen. Similarly, o...
Persons with type AB blood have one allele for A and the other for B that are dominant. In contrast, the O allele is recessive, and thus its expression is masked by the expression of the other alleles. The altered hemoglobin that causes sickle-celled anemia is inherited as a codominant trait. Heterozygous individuals express normal and sickle hemog...
Speckled chickens have alleles for both black and white features.Roan cattle have alleles for both red hair and white hair.Aug 3, 2023 · Codominance is a type of inheritance in which the expression of the two alleles (dominant and recessive) of the same gene results in the appearance of both traits in an individual instead of only one being dominant.
Nov 21, 2023 · Examples of Codominance in Humans. There are several examples of codominance in humans, including: Blood type; Sickle cell anemia; Humans have four phenotypes for blood type, type...
- What is codominance and incomplete dominance?Codominance and incomplete dominance are two types of inheritance patterns. In codominance both alleles are expressed equally. In incomplete domin...
- What is the meaning of codominant?Codominant is a type of inheritance pattern where both alleles inherited are expressed equally. Thus, heterozygotes express both alleles, rather th...
- What is an example of a codominant trait?An example of a codominant trait is blood type. There are four blood types, A, B, AB and o. Type A and B are both dominant to o, but when a person...
- What are examples of alleles?Alleles are different versions of a gene. For example, there are genes for eye color, and each gene has multiple alleles that produce eye colors li...
Codominance In Humans. When people think of incomplete dominance in humans, they often use wavy hair as an example, which is a result of a parent with straight hair and another with curly hair. Skin color, height, size of hands, and pitch of voice are all examples of incomplete dominance in humans.
Nov 8, 2020 · An example of codominance that occurs in humans is that of blood type. There are three different versions of the gene for proteins that appear on the outside of our blood cells and help our body to identify the cells as their own.
Like it? Share it! Codominance is observed when two different alleles of a specific single-gene trait are both expressed simultaneously. It follows non-Mendelian inheritance patterns. This article explains this phenomenon with the help of examples.
