Genotype of blood group $‘A'$ will be
${I^A}{I^A}$
${I^B}{I^B}$
${I^A}{I^A}$ or ${I^A}{I^O}$
${I^A}{I^O}$
A man with blood group ‘$AB$' marries a woman with ‘$O$' blood group. In this situation
The number of phenotypes in $ABO$ blood group is
Which idea is depicted by a cross in which the $F_1$ generation resembles both the parents?
$ABO$ 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?
If a human mother has ‘$O$' blood group, the foetus would die if the blood of foetus is
