Which of the following characteristics represent 'Inheritance of blood groups' in humans?

  1. Dominance
  2. Co-dominance
  3. Multiple allele
  4. Incomplete dominance

Correct answer: Co-dominance

Solution

Human blood groups are a classic example of co-dominance because both alleles in a heterozygote can be expressed at the same time. In the ABO system, the A and B alleles can both appear together as type AB.
