What is codominance?
- Codominance is an instant inside the DNA where both genes are expressed.
- Each organism receives alleles from their parents. There is a dominant allele and a recessive allele. In codominance both alleles are expressed, where usually the dominant allele would only be expressed.
- With both of the alleles equally strong, they are both expressed in the phenotype.
- As well both of the alleles are visible in the hybrid genotype.
- With both expressed the results of an organism look very interesting, there can be a clash of many colors in an animal.
- Some traits expressed in animals particularity could be different colors of their coats.
- Such as chickens when white chickens are crossed with black chickens, the result is a chicken with both black and white feathers.
- In humans when a person has the blood type AB it is an example of codominance. Both alleles are expressed.
