If two persons with 'AB' blood group marry and have children, the children could be classified as 'A' : 'AB' : 'B' in a ratio. Protein electrophoresis reveals presence of both 'A' and 'B' type proteins in 'AB' individuals. This is an example of:

  1. A
    Codominance
  2. B
    Incomplete dominance
  3. C
    Partial dominance
  4. D
    Complete dominance

Solution & Step-by-step Explanation
