Yes the baby can be type O because the father was heterozygous for his type B positive.
Yes - AB Parent has genotype IA IB . If the parent with B blood has the genotype IBi, which is entirely possible, then there is a chance that the baby would be IAi, and would have type A blood. Plus/minus has to do with the RH factor in blood, so you can't tell from the information given whether the baby could be "plus". If one of the parents is RH+, the baby could be as well.
Yes, an A+ parent and an O+ parent can have an A- baby. Blood type inheritance is determined by the ABO and Rh factor systems, where the ABO blood types are determined by alleles A, B, and O. The A+ parent can pass on either an A or O allele, while the O+ parent can only pass on an O allele. The combination of A from one parent and O from the other could result in an A blood type, and if the A+ parent carries the Rh negative factor, the baby could be A-.
No, in this scenario the possible blood types for the children are A- and B-. Positive refers to the presence of Rh factor in the blood. The Rh factor has to come from somewhere.
If one parent is B+ and the other parent is AB +, the child could be any blood type except type O. If the genotype of the parent with phenotype B is known, more detail could be given.
No...well, unless one of the parents is a chimera, but the chances of that are remote.
No - this is not possible. The baby must inherit the B allele from one of it's parents - but neither of these parents have one. The only possibilities with these parents are blood type A or O, depending on whether the parent with A-type blood is heterozygous, AO, or homozygous, AA.
Parents should re-test their blood types to check if there was any error in their past result. there is no way to have A blood type baby if both were O
No but it can have a type: +TJ)T(U34tWEG
No, the blood types a and b are dominant alleles and would mask the recessive o blood type.
yes it is possible if one person in parent with A blood group
then the baby will be O plus, or AB plus , I think .
O plus.
