Question

In the human blood grouping, the four basic blood types are type A, type B, type AB, and type O. The blood proteins A and B are :

(a) simple dominant and recessive traits (b) incomplete dominant traits

(c) codominant traits (d) sex-linked traits

Answer 1

The correct option is C

Explanation of the correct option:

1. ABO blood types in human is a classic example of multiple allelism and codominance where more than two allele forms are present for a trait and both A and B allele are dominant over the I allele.
2. The ABO blood group system classifies blood types according to the different types of antigens in the red blood cells and antibodies in the plasma.
3. They use the ABO system alongside the RhD antigen status to determine which blood type or types will match for a safe red blood cell transfusion.

Explanation of the incorrect option:

Option A,B and D didnot satisfy the appropriate explanation of the given question.

Final answer: In the human blood grouping, the four basic blood types are type A, type B, type AB, and type O. The blood proteins A and B are codominant proteins.
