It could be if its second or subsequent pregnancy and first baby was Rh pos and mum did not have any antenatal care or prophylactic anti-D within 72 hours of delivery.
This is rare though as most women have good care throughout pregnancy and there is a national programme to ensure women are given this injection as/when required.
The baby could be either B positive or O positive. The baby's blood type is determined by the combination of genes from the mother and father. Since the father's blood type is O positive, the baby has a chance of inheriting either B or O from the mother.
The baby can have either A positive or O positive blood type.
No. For a person to be "O" blood type, they have a phenotype of O, which can only come about if they have a genotype of OO. If both mother and father are O's then they have no B that they can donate to the baby.
There are many possibilities, but two things are certain: at least one parent must be type A or AB, and at least one parent must be Rh + A child with blood type A+ can have the following combinations of parents: Mother A+, Father A+ Mother A+, Father A- Mother A-, Father A+ Mother A+, Father B+ Mother A+, Father B- Mother A-, Father B+ Mother A+, Father AB+ Mother A+, Father AB- Mother A-, Father AB+ Mother A+, Father O+ Mother A+, Father O- Mother A-, Father O+ Mother B+, Father A+ Mother B+, Father A- Mother B-, Father A+ Mother B+, Father AB+ Mother B+, Father AB- Mother B-, Father AB+ Mother AB+, Father A+ Mother AB+, Father A- Mother AB-, Father A+ Mother AB+, Father B+ Mother AB+, Father B- Mother AB-, Father B+ Mother AB+, Father AB+ Mother AB+, Father AB- Mother AB-, Father AB+ Mother AB+, Father O+ Mother AB+, Father O- Mother AB-, Father O+ Mother O+, Father A+ Mother O+, Father A- Mother O-, Father A+ Mother O+, Father AB+ Mother O+, Father AB- Mother O-, Father AB+
Before you make rash decisions, make sure all tests are confirmed. First, The AB negative mother should be able to give birth to A-.A+,B-,B+,AB-,AB+ child. The mother is the one that can not, if all the tests are correct, have an O child. The father, if he is A -, can only have A-,A+,B-,B+,AB-,AB+.O-,O+.Now let me explain. There are two slots for A,B or empty(O). The father can be AO, or AA in this case. The mother is AB. She has to contribute either the A or the B, usually. Please notice the usually.Final answer, no because of the mother's contribution unless there is a mutation.
O+
Yes. The mother would have to be either B or AB.
Don't see why not - my hubby and I are A+ and A- and son is O+
can an o positive and an o negative make an a positive baby
O positive
no
yes
o positive
Yes. The father's phenotype is AO+*; the mother's is OO--.
yes
yes
no
