If two persons with ‘AB’ blood group marry and have sufficiently large number of children these children could be classified as ‘A’ blood group: ‘AB’ blood group: ‘B’ blood group in 1 : 2 : 1 ratio. Modern technique of protein electrophoresis reveals presence of both ‘A’ and ‘B’ type proteins in ‘AB’ blood group individuals. This is an example of :

ABO blood group system in human beings is an example of codominant, dominant recessive and multiple alletes. Blood groups are controlled by the gene I located on 9th chromosome that has 3 multiple alleles, out of which any two are found in a person. In codominance both gene express it self completely.

Explanation:
Codominance:
Codominance is a genetic concept where both alleles of a gene are fully expressed in a heterozygous individual. This means that both traits are visible in the offspring.
AB Blood Group Example:
- In the case of the 'AB' blood group, individuals inherit one 'A' allele and one 'B' allele from their parents.
- When two individuals with 'AB' blood group (genotype AB) marry and have children, the children can inherit the 'A' allele from one parent and the 'B' allele from the other parent.
- The modern technique of protein electrophoresis reveals the presence of both 'A' and 'B' type proteins in 'AB' blood group individuals, indicating that both alleles are expressed equally.
Ratio of Blood Groups:
- When two 'AB' individuals have children, the offspring can be classified into three types: 'A' blood group (genotype AA), 'AB' blood group (genotype AB), and 'B' blood group (genotype BB).
- The children will be classified in a 1:2:1 ratio, with 'AB' blood group individuals showing both 'A' and 'B' type proteins.
Therefore, the example of 'AB' blood group inheritance demonstrates codominance, where both 'A' and 'B' alleles are fully expressed in the offspring.
