yes, since A and B blood are co-dominant the parents of the baby hould have the genetic overcross of BB with one B being the a blood gene and the other being the b blood gene. also under rare occasions, the baby may take traits from grandparent or farther back since the genes in the parent go back to early times.
What else can I help you with?
If both parents are O positive can they have a child that is A positive?
No. If both parents are type O, the child will be O. If both are A, the child can be either A or O. If both are B, the child can be either B or O. If both are AB, the child can be A, B, or AB (but not O).
Can parents with a positive blood have b positive child?
If they both have type A blood, they cannot have a child type B.
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.
Can a b positive and a positive have a b negative child?
No. If both parents are positive, the child will be positive. If both parents are negative, the child will be negative. Parents who are negative and positive can have children who are either positive or negative. '+' + '+' = '+' '-' + '-' = '-' '+' + '-' = '-' or '+'
Can parents both both type blood o positive have a child with b positive?
yes
Can parents b positive and O positive have a b negative child?
Yes, it is possible for parents with blood types B positive and O positive to have a child with blood type B negative. This can occur if the parents are both carriers of the negative Rh factor and pass it on to the child.
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 that are both a negative have an ab positive child?
No. If both parents are A negative the child can only be A negative or O negative. If the child is AB positive at least one parent must have type B or AB blood and at least one must be RH positive.
How can a baby have b negative blood when both parents are b positive?
If both parents have Type B blood the only blood type the child can have is either B or O not looking at whether one of the parents is negative or not.
If both parents are blood type A positive and B positive will the child have any problem?
It is always possible, but normally not (as was the case with myself). The Child Can have A, B, or AB blood types.
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 both parents with A positive have a child with AB positive?
No. If two parents both have A blood then they are either AA or Ai. This means they can have a child with AA, Ai, or ii (O blood). To get AB there must be a B somewhere.
