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.
Yes, it is possible for a blood type B negative man to father a blood type A positive child. The ABO blood type system is inherited from both parents, with each parent passing on one of their two ABO genes to their child. This means that the child could inherit an A gene from the mother and a B gene from the father, resulting in a blood type of A positive.
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.
The father can have any variety of blood type. The only rare complication could occur if the father had A or B group blood, where after birth the mothers immune system attacks the babies red blood cells if it is either A or B. However, this is rare and not usually serious. You may be concerned about "Haemolytic disease of the Newborn" this mainly happens in Rheus D Negative mothers i.e. blood types A, B, AB or O negative if the baby is Rhesus D positive e.g. O positive. Plus the mother must have previously been exposed to Rhesus D positive blood e.g. previous chilbirth. But in this day and age it is very uncommon as it can be prevented both before and after birth. So you can have a baby no matter what blood type the father is.
The baby can have either A positive or O positive blood type.
If the child is Rh positive, and it is the mother's second child, the mother's antibodies will attack the child's red blood cells when the blood becomes mixed during labor. An injection called RhoGAM will be administered to the mother right before delivery to prevent any attack of fetal red blood cells.
Yes, it is possible for a mother with A positive blood and a father with O positive blood to have a baby with A negative blood. The baby would inherit one A allele from the mother and one O allele from the father, resulting in A negative blood type.
Yes, a father with A negative blood can have a child with A positive blood. If he does, the mother must have a positive Rh factor, and the mother's blood type may be any of the possibilities.
No.
yes.
B positive or negative or, O positive or negative.
Yes, a mother with negative and a father with O positive can have a baby with B positive. If they do, the mother must have blood type B or AB.
yes
95% not.
I'm not sure how negative or positive is determined, but a B mother and O father can have a B child.
yes
No
No, because a baby gets their blood from their father, not their mother.
