Answer:
Correct Answer: B
Solution:
*The inheritance of blood groups in humans is characterized by dominance, co-dominance, and multiple alleles. Here’s a brief explanation of each:
a. Dominance: In the ABO blood group system, the A and B alleles are dominant over the O allele. b. Co-dominance: The A and B alleles are co-dominant, meaning that if an individual inherits both alleles (genotype AB), both A and B antigens are expressed on the surface of red blood cells. c. Multiple alleles: The ABO blood group system is controlled by a single gene with three different alleles (IA, IB, and i).
