If one parent has blood group $A$ and the other parent has blood group $B$, the offsprings have which blood group
$AB$
$O$
$BO$
$A, B, AB, O$
Between persons of which two blood groups is the blood transfusion not 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
Three children in a family have blood types $O$, $AB$ and $B$ respectively. What are the genotypes of their parents?
Blood group $‘B'$ will have alleles
$ABO$ blood groups in humans are controlled by the gene $I$. It has three alleles $ I^A, I^B$ and $i$. Since there are three different alleles, six different genotypes are possible. How many phenotypes can occur?
