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

Choose the most appropriate answer from the options given below :

$ABO$ blood grouping is controlled by gene I which has three alleles and show co­dominance. There are six genotypes. How many phenotypes in all are possible?

A woman of blood group ‘$O$' presented a baby of blood group ‘$O$' which she claimed as her child. She brought a suit against a man of `$AB$' group as the father of the child. Which statement is correct as per your judgement

In heterozygous condition, the individual expression of both the alleles in the phenotype is exemplified by

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

The plasma membrane of the red blood cells has ...$A$... polymers that protrude from its surface and the kind of sugar is controlled by the gene. The gene I has three alleles ...$B$... The alleles and produce a slightly different form of the sugars, while allele i doesn't produce any ...$C$...

Choose the correct option for $A, B$ and $C$
