Codominance: Meaning & Definition
Codominance is a form of genetic inheritance in which both alleles of a gene in a heterozygous organism are fully expressed without one being dominant over the other. This results in a phenotype that clearly shows both traits.
Key Features of Codominance:
Both alleles contribute equally to the phenotype.
No blending of traits (unlike incomplete dominance).
Traits appear simultaneously in heterozygous individuals.
Examples of Codominance:
Blood Type (AB Blood Group): A person inheriting both A and B alleles has blood type AB, where both antigens are expressed.
Roan Cattle: Cows with red and white hair patches instead of a mixed color.
Flower Colors: Some plants display both red and white petals instead of blending into pink.
