no, unless one of the parents has b blood it is impossible for the child to have b blood.
****
Yes, it is possible if for some reason one parent inherited the B gene which didn't manifest. If no B proteins are produced, blood typing tests will never say it's B. However, that person can still have the gene, just not produce the protein for some reason.
What else can I help you with?
Can two parents with O positive blood have a child with AB negative blood?
No. O is recessive. The parents would have to have A and B phenotypes in order for their child to have AB- blood.
Can o positive and o positive have b positive baby?
No, two parents with O type blood cannot have a child with B type blood. This is because O is recessive - meaning in order to have type O blood, you need to have two O alleles. Therefore if both parents have O blood, all their children have to have O type blood. In order to have a child with B type blood, at least one parent needs to have B or AB type blood - in order to donate the B allele to the child.
Can two parents with the o blood types have a child with the a blood type?
No, because A & B are dominants.
Is it possible for 2 parents with type b blood to have a child with Type 0 blood?
Yes, they can have a child with blood type AB, which is the rarest of the four types.
What some have o blood type where both parents are AB and B?
It is not possible for two parents with blood types AB and B to have a child with O blood type. A child's blood type is determined by the combination of their parents' genes, and O blood type requires both parents to have at least one O gene.
Can parents both blood type B positives have a child with O positive blood type?
Yes, two B positives can produce an O positive child.
Can parents both blood type b positive have a child with blood type ab positive?
Yes, it is possible for two parents with blood type B positive to have a child with blood type AB positive. This is because the child can inherit one B allele from each parent to make blood type AB.
What blood type must the parents of a B child be?
The parents must have both blood type B or blood type 0 and B.
Is it possible for two parents with type B blood to have with type O blood?
I assume the question is "Is it possible for two parents with type B blood to have a child with type O blood?" Yes they can, if both parents have BO genotype. The chance of the child having O blood is 25% in this case. Source: http://en.wikipedia.org/wiki/Blood_type
Is there a posibility to have a child that is blood type -A A couple who are blood type B and blood type O?
No. It is not possible for a child to have A if the parents are O blood type. If both parents have type O blood, then their children will also have type O blood. However, two parents with type A or type B blood (both the same or one of each) can sometimes have a child with type O blood. That is because the gene for type O blood is recessive. But they must carry the O type. However, two parents with type AB blood can have a child with type A, type B, or type AB blood, but cannot have a child with type O blood.
Can parents with b negative blood have a child with o positive blood?
If both parents are B- they can only have children who are B- and O-. One would have to be positive in order to have a child with positive blood.
How could two parents with blood types a and b have a child with o?
If the parents had the genotypes AO and BO, then they could have a child with Type O blood (there would be a 25% chance of this occurring).
