A woman with blood group O can have only one set of alleles that is OO (recessive) and man with blood group B can have alleles either as BB (homozygous) or BO (heterozygous).
If the man carries the allele BB, then all possible genotypes present in child will be BO. Hence, the chance of getting blood group as B will be 100%.
If the man carries the alleles BO, then possible genotypes in child will be BO and OO. Hence, in this case there will be 50% chances of getting blood group B and 50% chances of getting blood group O.
If the man carries the allele BB, then all possible genotypes present in child will be BO. Hence, the chance of getting blood group as B will be 100%.
