Detailed explanation-1: -If one of the children is type O, then the mother must have been IAi, because otherwise the child could only be type A. So, the father is ABO genotype ii, Rh type +/-, and the mother is ABO genotype IAi and Rh type +/-.
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: -Answer and Explanation: The possible phenotypes of the offspring between a man with blood type B and a woman with blood type A are A, B, O, and AB. Based on the Punnett Square, and depending on the genotypes of the parents, the offspring would have different blood types.
Detailed explanation-4: -The genotype of a woman with type A blood whose father has type O blood is AO. This is because the O blood allele is recessive and will only produce the O blood type of both alleles in a person are O.
