In terms of genetics, codominance is a sort of inheritance in which two distinct expressions (alleles) of the same gene result in distinct features in a person. Phenotypes:
The term "phenotype" describes a person's observable characteristics, such as height, eye color, and blood type.
The genomic make-up (genotype) of an individual as well as environmental influences affect their phenotypic.
In codominance, there are two possible phenotypes.
When both alleles at a gene locus are completely expressed in the phenotype, it is known as codominance, which is a heterozygous state.
Both phenotypes are partially dominant in codominance.
