If one parent has a blood type of B-positive and the other has A-positive can their child have B-negative?

No. A person's blood type is made of up contributions from both your mother and your father. O blood types (whether positive or negative) are really OO. So no matter whether you get the first O or the second O, all resulting children must be OO. For example, my mother is an OO, and my supposed father was an AO. I am a type B, so there is no way that I am that man's child (my mother just recently confirmed that there could have been someone else). Blood types resulting from my mother and "father" could be A (AO), or O (OO), but that is it. O is a recessionary gene, that is why a person with type O blood can only contribute O's to their children. In order to be type O, you must be an OO.

∙ 12y agoYes - this is quite possible. With Rh factors, the positive is the dominant allele. If both parents are heterozygous, Rh+Rh-, then they can have an Rh- child. The parent with blood type B also has to be heterozygous for this, BO.

To put it simply, both the B and A blood types can be BO and AO from an inheritance standpoint, meaning a child could be O. The same for the rh portion of the question, a child with one rh positive parent and one rh negative patient could be rh negative.

∙ 11y agoYes. Both parents would have to be heterozygous for blood group, AO and BO, so that each parent can pass an O allele to their offspring. The B positive parent would have to be heterozygous for rh factor, rh+ rh-, and would have passed the rh- allele to the offspring, so that the child's genotype will be OO/rh- rh- , and its phenotype is O negative.

My blood group is B positive and my fiance's blood group is Bnegative. is there is any medical problem?
Your RH factors don't match. It's something to consider, and could be a problem if you get pregnant, but it's nothing modern medicine can't easily cope with.
What type of blood for O r h postivtive?
The blood type will depend on the other parent. but the Rh factor will be + no matter what is it for the other parent.
Can your sisters be o blood group and yourself b blood group?
Yes, you can have a sister with blood type O and you can be blood type B. This can happen if you have one parent with type AB or B blood, and other parent with type O or B blood.
Can a o positive father have an AB negative child?
No. In order for someone to have AB blood, they must inherit the A from one parent and the B from the other. Therefore a parent with O blood could only have A, B or O children (depending on the blood type of the other parent).
Do your children have to have same blood as you?
No - children do not have to have the same blood type as the parents. For example, if one parent has blood type A and the other has blood type AB, the child might have A, B or AB blood types. (For the child to have B, the parent with blood type A would need to be heterozygous, Ao)
If the mother is Bpositive and the father is O positive what blood group will the baby be?
B+
My blood group is B positive and my fiance's blood group is Bnegative. is there is any medical problem?
Your RH factors don't match. It's something to consider, and could be a problem if you get pregnant, but it's nothing modern medicine can't easily cope with.
Can One parent with an o blood type and the other parent with an A blood type produce a b blood type?
Nope.
Can negative blood type parent and positive blood type parent have an Rh negative blood type child?
yes, absolutely
Can a parent with O negative blood type and a parent with A positive blood type have a baby with O positive blood type?
Of course!
Can b positive parent have child with a positive blood?
A B+ parent can have a child with A+ blood. The other parent must be type A or type AB for this to occur.
Can a parent with type a blood and a parent with type o blood have a child with type b blood?
well the answer and yes and no sometimes they have a and some times they don't
Can a parent with blood type B and a parent with blood type O have a child with blood type A?
well the answer and yes and no sometimes they have a and some times they don't
Can a parent o Blood and a parent B have a child with B?
yes
If the mother is B positive and the Father is O positive what will the baby be?
my blood group is bpositive and my husbands is o positive is this combination suitable for marriage
Can a parent with a positive and a parent with ab positive have a child with a negative blood?
rarely can be
What will the result of O- blood plus B?
For a transfusion - blood type O can donate to blood type B. However, blood type O cannot except B-type blood. For offspring, with one O parent and one B parent - the child could be blood type O or B depending on the genotype of the parent with B-type blood.
