yes but the A child would have to have a kid at a really early age
If my mother is b- and my dad is b+ could there be a child ab- please
yes
Could be B or could be O.
mother could be either B or AB and she could also be Negative or Positive.
No. The mother only has type O antigens and the father has type B (and possibly O). Neither of them could have supplied the type A antigens to the child.
Yes, this will depend on the father blood type, so for a child to be B-, the father could be either B or AB negative or positive.
It's possible that the child could be either A, B, AB, or O.
No
Yes! You could produce a child with either A or B blood.
I'm not sure how negative or positive is determined, but a B mother and O father can have a B child.
No, the child could only be O+ or O-.
If the mother is type A or AB (either positive or negative), they could be father and son. Depending on the mother's blood type, an O- father could have a child who is: A+, A-, B+, B-, O+, or O-.
