Identify the wrong statement with reference to the gene 'I' that controls ABO blood groups.
A person will have only two of the 3 alleles.
When IA and IB are present together, they express same type of sugar.
Allele 'i' does not produce any sugar.
The gene (I) has three alleles.
the gene (I) has three alleles: IA, IB, and i . Since humans are diploid, a person possesses any two of the three alleles . The allele 'i' does not produce any sugar . However, when IA and IB are present together, they both express their own types of sugars (not the same type) because of co-dominance . Therefore, the statement that they express the same type of sugar is incorrect.
