The genotypes of a husband and wife are $I^AI^B$ and $I^Ai$. Among the blood types of their children, how many different genotypes and phenotypes are possible?

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

As per $\mathrm{ABO}$ blood grouping system, the blood group of father is $\mathrm{B}^{+}$, mother is $\mathrm{A}^{+}$and child is $\mathrm{O}^{+}$. Their respective genotype can be

How many phenotype and genotypes are possible in ABO blood group systems?

If a child has $O$ type of blood group and the father $B$ type, the genotype of the father will be

A man with blood group ‘$AB$' marries a woman with ‘$O$' blood group. In this situation
