Detailed explanation-1: -The chance for A blood group is 37.5% + 12.5% = 50% . The chance for B blood group is 12.5% . The chance for AB blood group is 37.5% .
Detailed explanation-2: -One parent with A and another with B can produce a child with A, B, AB or O blood types. If one parent has A and another has AB, they can either produce a child with A, B or AB blood types. If one parent has A and another has O, they can either produce a child with A or O blood types.
Detailed explanation-3: -Finally, the parental genotypes in option (D), IAIB and IAIB, have a 50 percent chance of producing offspring with blood type AB, a 25 percent chance of producing offspring with blood type A, and a 25 percent chance of producing offspring with blood type B.
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.
