In a marriage between male with blood group $A$ and female with blood group $B$, the progeny had either blood group $AB$ or $B$. What could be the possible genotype of parents ?
$\mathrm{I}^{\mathrm{A}{i}}$ (Male) $: \mathrm{I}^{\mathrm{B}} \mathrm{I}^{\mathrm{B}}(\text { Female })$
$\mathrm{I}^{\mathrm{A}} \mathrm{I}^{\mathrm{A}}$ (Male) $: \mathrm{I}^{\mathrm{B}} \mathrm{I}^{\mathrm{B}}(\text { Female })$
$\mathrm{I}^{\mathrm{A}} \mathrm{I}^{\mathrm{A}}(\text { Male }): \mathrm{I}^{\mathrm{B}}$ i (Female)
$\mathrm{I}^{\mathrm{A}{i}}$ (Male) $: \mathrm{I}^{\mathrm{B}_{1}}$ (Female)
The father has blood group $AB$ and mother $‘O'$. The child is supposed to have which of the following bloodgroups
Which idea is depicted by a cross in which the $F_1$ generation resembles both the parents?
$ABO$ blood groups are controlled by the gene
A gene showing codominance has
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
