Vedclass · Answer

(B) The blood group $O$ is represented by the genotype $I^OI^O$. Since a child inherits one allele from each parent,the child must have received one $I^O$ allele from the father and one $I^O$ allele from the mother. Therefore,the father must possess at least one $I^O$ allele. If the father has blood group $B$,his possible genotypes are $I^BI^B$ (homozygous) or $I^BI^O$ (heterozygous). However,if the father's genotype were $I^BI^B$,he could only pass the $I^B$ allele to his offspring,making it impossible for the child to have blood group $O$. Thus,the father's genotype cannot be $I^BI^B$ if the child has blood group $O$.
