Could a parent with blood type O and A parent with blood type B have a child with type A blood?

Two parents with A blood type can produce a child with either A or O blood types. Two parents with B blood type can produce a child with either B or O blood type. One parent with A and another with B can produce a child with A, B, AB or O blood types….ABO Blood Type Calculator.

What is the probability of a child having type O blood if one of the parents is heterozygous for type A blood and the other is heterozygous for Type B?

If the father is heterozygous, there is a 50\% probability for a blood type A child and a 50\% probability for a blood type O child….Blood types.

Can a mother with type O blood give birth to a child with type A blood?

ABO incompatibility can occur only if a woman with type O blood has a baby whose blood is type A, type B, or type AB. If a baby is type O there won’t be a problem with a negative immune response because type O blood cells don’t have immune-response triggering antigens.

Can only get blood from a type O donor?

Donors with blood type O… can donate to recipients with blood types A, B, AB and O (O is the universal donor: donors with O blood are compatible with any other blood type)

What is a child’s blood type if the mother has AO?

So the child’s blood type depends on the alleles that the parents carry. For instance, if the mother has the blood type AO and father has blood type BO, the child can end up with any one of the blood groups: A (25\%), B (25\%), AB (25\%) or O (50\%).

What blood type can a father pass to his child?

Mother with AB blood type can either pass the A or B allele to the baby. Likewise, a father with O blood type can only pass O allele to the baby. If both parents belong to the blood group O, the child will also belong to the O blood group. Two A blood group parents can give their child either A or O blood group.

How do you use blood types to determine paternity?

Using Blood Types as a Cheap Paternity Test. For example, if the child is A and the mother is O, the father MUST be A or AB. It is biologically impossible for a man with B or O blood to have fathered this child. NOTE: The two blank cells represent impossible combinations between mother and child, regardless of the father.

How do you determine the blood type of a child?

PATERNITY CAN BE RULED OUT BASED ON BLOOD TYPE MATCHING IN MANY CASES. The calculator is used to determine either: The ABO blood type of the child when the blood type of the mother and the father are known (top chart), or The ABO blood type of the father if the blood type of the mother and the child are known (bottom chart).
