What else can I help you with?
Father has b positive and mother o negative can the baby be a negative?
No, the baby cannot be A-. A and B genotypes are codominant and O is recessive. Since the father is B and not AB, his genotype must be either BB or BO. The mother is OO. So there is no way for them to have an AO or AA baby. The baby can be Rhesus negative however, because the father may be heterozygous for the Rhesus factor.
Can 2 sisters have O positive and O negative blood types and have the same mother?
If their mother and father had different Rhesus factors, yes.
What blood types would your parents have to be to have a child with A positive blood type?
Discounting rare but possible mutations the following holds true. Parents blood groups A and A, A and B, A and O, B and B, B and O, O and O can produce type O blood in their children. The rhesus factor (Rhesus positive/rhesus negative) depends on the rhesus pairing in the parents as follows: Father rhesus positive, mother rhesus positive or rhesus negative = rhesus positive or rhesus negative Father rhesus negative, mother rhesus positive = rhesus positive or rhesus negative Father rhesus negative, mother rhesus negative = rhesus negative Example: A rhesus positive father and rhesus positive mother of blood type A and O respectively could produce an O positive child, as could a rhesus positive father and rhesus negative mother both of blood group O.

Can an o negative blood type father parent an o positive child?
Sure, if the mother is Rhesus (D) positive
Can a A- mom have a AB- child with a O plus dad?
No. The mother must be either AO or AA, and the father OO. No combination of these can give rise to an AB child. However, a negative mother and a positive father can have a negative child, by rhesus factors, if the father has genotype +-.
What are the problems if a man with o negative blood group marry a women with a positive blood group?
When they become pregnant there should not be any problems related to the rhesus blood groups - this would only be a potential problem if the mother was negative, and the father was positive.
What are the implications of having type a negative blood?
The negative blood comes from the rhesus scale. So type A negative blood means you are rH negative. This poses a potential problem during pregnancy if the mother is rH negative and the father is rH positive. In that case the mother will receive a rhogam shot during pregnancy and right after birth to prevent the potential mixing of blood between mother and child from causing a serious reaction in the mother's body.
If parent both blood group B positive is there any health problem for child?
No. When the mother has a negative blood type and the father has a positive blood type, this could lead to Rhesus factor in the foetus. When both parents are positive blood group, there isn't a risk of becoming rhesus.
What blood type will the child be with parents blood type O positive father and mother O positive?
The baby can only be an O Blood Group as both parents can only be carrying 'O' type genes. The baby would have a 75% chance of being an O positive and a 25% chance of being an O negative. This is because the mother can only pass on a Rhesus negative gene but the father might either have two Rhesus positive genes or one Rhesus positive and one Rhesus negative. If the first is true the child will only be O positive, if the second is true it could be O positive or O negative depending on which gene the father passes.
If mother is b plus and the father is a- could the baby be ab plus?
It's called "positive" and "negative" - yes the "A" father and "B" mother can each give a gene to produce "AB"; The Rhesus gene is either positive or negative so the baby could get either.
What blood type will the child be with parents blood type o negative mother and father o positive?
The baby can only be an O Blood Group as both parents can only be carrying 'O' type genes. The baby would have a 75% chance of being an O positive and a 25% chance of being an O negative. This is because the mother can only pass on a Rhesus negative gene but the father might either have two Rhesus positive genes or one Rhesus positive and one Rhesus negative. If the first is true the child will only be O positive, if the second is true it could be O positive or O negative depending on which gene the father passes.
What problems might occur if a mother is rhesus-negative and the father is rhesus-positive?
It is possible for there to be problems with a pregnancy. If mother's blood type is negative and the father's is positive, and the baby is positive, her blood type may begin to attack the child. Make sure she checks with her doctor regularly during a pregnancy.
