If two persons with 'AB' blood group marry and have a sufficiently large number of a 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
Codominance
Incomplete dominance
Partial dominance
Compelete dominance
