$A$ : Blood group phenotype is controlled by presence or absence of antigens present on surface coating of $RBC$.
$R$ : These antigens are of three types and found in the oligosaccharides rich head regions of a glycophorin
Assertion and Reason both are correct and also correct explanation.

Both Assertion and Reason are incorrect.
If a child has $O$ type of blood group and the father $B$ type, the genotype of the father will be
Which of the following is genetically dominant in man
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
All of this obeys Mendel's laws except
Three children in a family have blood types $O$, $AB$ and $B$ respectively. What are the genotypes of their parents?
