What is the result of Codominance?
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.
How could you tell it is showing Codominance?
In codominance, both alleles are completely expressed. If you crossed a red flower with a white one and the alleles were codominant, you might get flowers that are red and white in patches. If the alleles were incompletely dominant, the flowers would be pink because the traits blend.
What phenotype does Codominance result in?
Indeed, “codominance” is the specific term for a system in which an allele from each homozygote parent combines in the offspring, and the offspring simultaneously demonstrates both phenotypes. An example of codominance occurs in the human ABO blood group system….Codominance.
| Blood Type | Related Genotype(s) |
|---|---|
| O | OO |
What type of dominance is demonstrated by the Rh factor?
simple dominance
The blood Rh factor (+ or -) displays an inheritance pattern of simple dominance.
How incomplete dominance is different from codominance?
In codominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.
How does codominance compare to incomplete dominance?
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.
Is codominance a type of incomplete dominance?
What blood types show complete dominance?
The human ABO blood group system exhibits codominance. The system consists of three alleles A, B, and O. Both A and B are dominant in relation to O, and therefore blood group A can have the genotype AA or AO. Blood group B can have the genotype BB or BO.
What do you mean by incomplete dominance explain with suitable examples?
When none of the factors of a gene is dominant, the phenotype of a heterozygous dominant individual is a blend of dominant and recessive traits. This is called as incomplete dominance. For example, flower colour in Mirabilis jalapa. The red flower is the dominant character and the white flower is recessive character.
Which is an example of codominance in humans?
Codominance. Closely related to incomplete dominance is codominance, in which both alleles are simultaneously expressed in the heterozygote. We can see an example of codominance in the MN blood groups of humans (less famous than the ABO blood groups, but still important!).
Why is the ABO blood group an example of codominance?
Codominance occurs when both alleles show dominance, as in the case of the AB blood type (IA IB) in humans. Furthermore, the human ABO blood groups represent another deviation from Mendelian simplicity since there are more than two alleles (A, B, and O) for this particular trait.

What is the difference between incomplete dominance and codominance?
Incomplete Dominance and Codominance both are the two types of inheritance, in which one allele (or a version of a gene) does not completely dominant on another allele. In this phenomenon, one Allele does not mask the effects of other alleles.
Why are red and white flowers dominant in codominance?
In the result of codominance phenomenon, both different alleles of flower plants produce new flower plant with red and white patches on the petals of the flower. Because both red and white flowers alleles are dominant along with each other.
