No.
If the child is AB, it must have inherited the A from one parent and the B from the other. If the father is O he has OO - and so cannot give the child an A or B.
The child will be A or B or AB, Rh+ or Rh- . So yes, the child can be A-.
If the mother is A negative, and the father is B positive, they could have children who are A negative, A positive, B negative, B positive, AB negative, AB positive, O negative, or O positive.
Given that the mother's DNA is A and the child is A positive, the father's DNA must also contain the A antigen. The father could be A positive, A negative, AB positive, or AB negative.
No, the father would have to have B or AB.
Yes.
No, an O-group parent cannot have an AB-group child at all.
Yes, it is possible for parents who are AB positive and B positive to have a child who is A negative. This is because a child can inherit one A and one Rh negative gene from the parents, resulting in blood type A negative.
yes
No, an O-group parent cannot have an AB-group child at all.
Yes it is possible...
for sure
An AB+ and B- couple can't have a child with blood type O. They can have children with blood types A, B, or AB, and can have children with Rh negative or Rh positive blood.
