We are looking for the possible blood types of DAD.
Available information:
O positive
The blood would be A+, the child's is always pretty much what the Father's is.
Yes. The mother would have to be either B or AB.
The child would most likely have either blood type A positive or B positive. A child inherits one blood type allele from each parent, so with an AB negative mother and an O positive father, the child could receive the A allele from the mother and the O allele from the father, resulting in blood type A positive. Alternatively, the child could receive the B allele from the mother and the O allele from the father, resulting in blood type B positive.
It would all depend on the Dominant and Recessive blood type genes in the mother and father it is near improbable to tell unless you take a blood sample to test the blood type. == A rhesus negative mother and positive father can produce either a rhesus negative or positive child. A type A and type O parental combination will only produce either type A or type O children. So an A- mother and O+ father will normally produce offspring having the possible blood groups of A+ or A- or O+ or O-. See the link for a full explanation.
A+
Probably AB+ blood.
o blood
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.
O positive
either "AB" or "A".
The child's blood type could be B positive or O positive.
If the father's blood type is O positive and the mother's blood type is B positive, a child could have type B or type O blood, and the Rh factor could be positive or negative.
B positive or negative or, O positive or negative.
With a mother with AB Positive blood type and a father with an O Positive blood type, there are four possibilities for the offspring's blood type. The child of this pairing could have A positive or negative, or B positive or negative type blood.
the child's blood group will be AB-.
Anything but AB.
