If two persons with' AB' blood group marry and have the sufficiently large number of children, these children could be classified as 'A' blood group: 'AB' blood group: 'B' blood group in 1: 2: 1 ratio. The modern technique of protein electrophoresis reveals the presence of both' A' and 'B' type proteins in 'AB' blood group individuals. This is an example of:
1. Incomplete dominance
2. Partial dominance
3. Complete dominance
4. Codominance
