1. When lA and lB are present together, they both express their own types of sugars, this is because of co-dominance.
2.The alleles lA and lB produce a slightly different form of the sugar, while i does nol produce any sugar.

Consider the following statements about the ABO blood grouping in hum...
Incorrect Pair: B and C
Explanation:
The ABO blood grouping system in humans is controlled by the gene I, which has three alleles: IA, IB, and i. Let's analyze each statement to determine the incorrect pair.
A. ABO blood groups are controlled by gene I, having three alleles lA, lB and i.
This statement is correct. The ABO blood groups are indeed controlled by the gene I, which has three alleles: IA, IB, and i. The alleles IA and IB are codominant, while the allele i is recessive.
B. IA and IB are completely dominant over i but lA and lB show incomplete dominance when they are present together.
This statement is correct. Both IA and IB alleles are completely dominant over the i allele, meaning that if an individual carries either IA or IB allele, their corresponding antigen (A or B) will be expressed on their red blood cells. However, when IA and IB alleles are present together, they exhibit incomplete dominance. The resulting phenotype is AB, where both A and B antigens are expressed on the red blood cells.
C. The alleles lA and lB produce almost similar form of sugar but the i allele produce a completely different sugar.
This statement is incorrect. The IA and IB alleles produce slightly different forms of sugar, which are recognized by the immune system. The IA allele produces a form of sugar that is recognized as the A antigen, while the IB allele produces a form of sugar that is recognized as the B antigen. On the other hand, the i allele does not produce any sugar and is considered a null allele. It does not produce any antigen, resulting in blood type O.
D. A total of six different genotypes and four phenotypes are possible.
This statement is correct. The ABO blood group system allows for six different genotypes: IAIA, IAIB, IBIB, IAi, IBi, and ii. These genotypes give rise to four different phenotypes: blood types A, B, AB, and O.
Therefore, the correct answer is option B, as statement C is incorrect.
