In the scenario of co-dominance where both IA and IB alleles are present, they express their own types of sugars simultaneously. This occurrence is due to the unique nature of co-dominance, where neither allele suppresses the other, resulting in the expression of both sugar types. This leads to red blood cells displaying both A and B types of sugars, showcasing a co-dominant inheritance pattern.

Understanding Co-Dominance
Co-dominance is a genetic scenario where both alleles in a heterozygous individual are fully expressed, resulting in a phenotype that displays characteristics of both alleles.
Key Concepts of Co-Dominance
- Alleles IA and IB: In the context of blood types, IA and IB are co-dominant alleles responsible for the A and B antigens, respectively.
- Presence of Both Alleles: When an individual possesses both IA and IB alleles, neither allele masks the other. Instead, both alleles contribute to the phenotype.
What Happens in Co-Dominance?
- Expression of Antigens: In an individual with both IA and IB, both A and B antigens are produced on the surface of red blood cells.
- Resulting Blood Type: The presence of both antigens results in the AB blood type, which is a classic example of co-dominance.
Why Option C is Correct
- Both Alleles Expressed: When both IA and IB alleles are present, both express their sugar types on the cell surface. This leads to the individual having the AB blood type.
- Distinct Phenotype: The result is a distinct phenotype where both characteristics are observable, showcasing the co-dominant nature of these alleles.
Conclusion
In summary, when both IA and IB alleles are present, the individual expresses both sugar types, leading to the AB blood type. This exemplifies co-dominance, where neither allele is dominant, and both traits are fully manifested. Thus, the correct answer is indeed option 'C'.
