What blood type will a child have if both parents are B positive?
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. If one parent has A and another has AB, they can either produce a child with A, B or AB blood types.
Why do me and my sister have different blood types?
Each biological parent donates one of their two ABO alleles to their child. Identical twins will always have the same blood type because they were created from the same fertilized egg (fraternal twins can have different blood types — again, providing the parents do — because they are created by two fertilized eggs).
Why is my blood type different from my siblings?
