Codominance is an inheritance pattern. Human blood type is an example of CODOMINANCE where both the A and B blood types can be expressed.
<h3>What is codominance?</h3>
Codominance refers to the inheritance pattern in which a phenotype expresses two alternative variants coded by two alleles inherited from each homozygous parent.
When two individuals, that are homozygous and different for a trait, are crossed they produce heterozygous individuals.
These progenies express both parental phenotypes, as it is an additive expression of their parents' genes. Both alleles are equally expressed.
The is not complete dominance in these cases.
In the case of blood, the I gene determines the blood type of a person.
→ I is <u>completely dominant </u>over the i recessive allele.
→ Allele I can be either IA and IB, which are <u>codominant</u>.
- The person IAi expresses the A blood type ⇒ complete dominance
- The person IBi expresses the B blood type ⇒ complete dominance
- The person IAIB expresses the AB blood type ⇒ codominance ⇒ both alleles are simultaneously expressed
Human blood type is an example of CODOMINANCE where both the A and B blood types can be expressed.
