The most popularly known blood grouping is the $ABO$ grouping. It is named $ABO$ and not $ABC$, because $“O”$ in it refers to having
overdominance of this type on the genes for $A$ and $B$ types
one antibody only - either anti - $A$ or anti - $ B$ on the $RBCs$
no antigens $A$ and $B$ on $RBCs$
other antigens besides $A$ and $B$ on $RBCs.$
If one parent belongs to $‘A'$ blood group and the other to $‘O'$ blood group, their children possibly represent
Mother and father both have blood group $‘A’$. They have two children one with blood group $‘O’$ and second one with blood group $‘A’$. They have
In heterozygous condition, the individual expression of both the alleles in the phenotype is exemplified by
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?
$ABO$ 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?
