If two persons with the ‘AB’ blood group marry and have a 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. The modern technique of protein electrophoresis reveals the presence of both ‘A’ and ‘B’ type proteins in ‘AB’ blood group individuals.

The correct option is D Codominance
The correct option is D.
The explanation for the Correct option:
- 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.
- Both phenotypes are partially dominant in codominance.
- The heterozygous person, however, displays both traits.
- The ABO blood group system is a prevalent illustration.
- Blood type genes are recessive to both A and B and have three alleles: A, B, and O type.
- The A and B alleles are mutually dominant.
- A person has type AB blood when both A and B are present.
- Whether an allele is dominant or recessive depends on the homologous chromosomes in codominance.
- When two protein-producing alleles are present on a homologous chromosome, both will be produced, resulting in a distinct phenotype or set of traits than a homozygote.
The explanations for the Incorrect option:
Option A:
- In complete dominance, the phenotype only displays one allele from the genotype.
- When codominance exists, the phenotype exhibits both alleles present in the genotype.
- A mixture of the genotype's alleles can be visible in the phenotype in incomplete dominance.
- Complete dominance is a condition where the effect of the recessive allele is completely hidden by the dominant allele.
- The polar opposite of codominance is this. Antigen A, for instance, is present in blood types A and B.
- The IA designation for this allele.
Option B:
- When both alleles of a gene are only partially expressed at a locus, it is known as incomplete dominance.
- This sort of gene interaction frequently produces an intermediate or distinct phenotype.
- Additionally called partial dominance.
- For instance, the gene for the color red predominates over the allele for the color white in roses.
- However, the heterozygous blooms that carry both alleles are pink.
Option C:
- When both alleles of a gene are only partially expressed at a locus, it is known as incomplete dominance.
- This sort of gene interaction frequently produces an intermediate or distinct phenotype.
- Additionally called partial dominance.
- For instance, the gene for the color red predominates over the allele for the color white in roses.
- However, the heterozygous blooms that carry both alleles are pink.
Final answer: If two persons with the ‘AB’ blood group marry and have a 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. Codominance is the modern technique of protein electrophoresis that reveals the presence of both ‘A’ and ‘B’ type proteins in ‘AB’ blood group individuals.
