Detailed explanation-1: -Answer and Explanation: Because the child has blood type O, the child’s genotype must be OO. The mother is blood type B, which means that her genotype could be BB or BO.
Detailed explanation-2: -Genotypes BB and BO have Type B Blood Genotypes BB and BO refer to individuals having either two “B” alleles for blood type, or one “B” allele and one “O” allele. Both of those genotypes results in having Type B blood. The BO genotype results in Type B blood because B is dominant over O.
Detailed explanation-3: -The father with B group can have the genotype IOIB or IBIB . The child with blood group O will have the genotype ii, one from each parent. Hence the father has the genotype IOIB.
Detailed explanation-4: -Believe it or not, in this case having a blood type different from either parent is by far the most common result. In most cases, an O parent and an AB parent will have only A or B kids.
