Vedclass · Answer

(C) The human blood group system ($ABO$ blood grouping) is controlled by the gene '$I$'. The gene '$I$' has three alleles: $I^A$,$I^B$,and $i$.- $A$ person with blood group '$O$' has the genotype '$ii$'.- This means the child must have inherited one '$i$' allele from each parent.- If one parent has blood group '$AB$',their genotype is $I^A I^B$. They can only pass on either the $I^A$ allele or the $I^B$ allele to their offspring.- Therefore,a parent with blood group '$AB$' cannot produce a child with blood group '$O$' because they lack the '$i$' allele.

If a child has blood group '$O$',which of the following blood groups cannot be present in their parents?
