If two persons with $‘AB’$ blood group marry and have 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. Modern technique of protein electrophoresis reveals presence of both $‘A’$ and $‘B’$ type proteins in $‘AB’$ blood group individuals.This in an example of
partial dominance
complete dominance
codominance
incomplete dominance.
All of this obeys Mendel's laws except
Progeny with blood group $‘O’$ can not be obtained in cross
