No if i am not mistaken people with O blood have to have their blood type back, however people with O blood can give to anyone in need.
No. It is impossible, given those blood types, for the offspring to be O positive.
In that given scenario, the possible blood types of the child are: A-, A+, O+ and O-.So Yes, it is possible to have a child with A positive with 25%.
No. Either the mother or the father (or both) must have type A or AB blood in order for the child to inherit type A blood. Independently of their ABO blood type, either or both parents must also be Rh positive for the child to be Rh positive. In the case given, the baby could be Rh positive since the mother is Rh positive but it could not be type A since neither parent has type A or AB blood.
No possible way to tell. The A and O are phenotypes, meaning that their personal blood type has the respective characteristics. There is also their genotypes, which they get from their parents and can be two different types, although one of the two will be their genotype. So it is possible that A type blood came from an A parent and a B parent. The O blood could have come from an O parent and an AB parent. It is conceivable that those two could have four children, all with different blood types. The rhesus factor ( positive or negative ) is another complication.
The child can have either Rh positive or Rh negative blood. More information is needed on the mother's genotype to know for sure. With the information currently given, the child has a 25% chance of being Rh negative.
The critical information for mother/father is the "positive" at the end of the blood type. The refers to the rh factor, which if an rh Negative mother conceives a child with an rh positive father, the fetus may have rh positive blood. The mother's body will fight the baby's body and can cause problems. If the rh factors are different, the mother will be given two doses of RhoGam, which will allow the pregnancy to be carried to term without problems. However, A positive, and B positive are compatible, and will not need this.
Negative blood can be given to someone with positive blood. Positive blood CANNOT be given to someone with negative blood.
Yes. If the mother is O, then her phenotype is O, and her genotype must be OO. If the father is B, then his phenotype is B, and his genotype could be BB or BO. If the father's genotype is BO, then he could pass his O to the child along with the mother's O, allowing the baby to be O. In fact statistically, half of their children would be B, and half would be O. The baby could inherit the positive from his father, who has positive. NB: In this particular scenario, since the mother is negative and the baby is positive, there is a chance of a blood match incompatibility between the two, and the mother should be given RhoGam to prevent her making antibodies against the positive antigens in the fetus blood.
The advantage of the blood group O positive is that O positive blood can be given to any blood group. This is especially important when it comes to blood shortages.
A Positive can RECEIVE A+, A-, O+, and O- blood. A Positive can DONATE to A+, and AB+ O Positive can DONATE to A+, B+, O+, and AB+. O Positive can RECEIVE O+ and O- blood only. As far as conception and what the child would be and if there would be any complications directly linked to the blood type, The possible combinations of blood type for the child would be AO+ (thus being "A Positive) or OO+ (Thus being "O Positive) and since both blood types are "+" (meaning they both contain the protein), then there should be no incompatibility problems.
AB positive; a person with rhesus-negative blood can have an adverse reaction if given rhesus-positive blood.
The most severe form of erythroblastosis fetalis is that resulting from Rh incompatibility. But you can have erythroblastosis fetalis with ABO incompatibility as well. And this can occur with any child, even the first, and even with an Rh-negative child. However, if you're referring to Rh-incompatibility erythroblastosis fetalis, the answer to your question is, "Not usually" (assuming she hasn't had a previous Rh-positive child). In Rh-incompatibility, erythroblastosis fetalis occurs with the woman's second Rh-positive child. The first Rh-positive child's blood gets into the mother's bloodstream (e.g. at childbirth). The mother's blood makes antibodies to Rh. Since the first child is already born, this does not affect the first child. Then, when she has a second Rh-positive child, her antibodies cross the placenta and attack that child's blood cells. On the other hand, if the mother is exposed to the Rh factor of the first child's blood earlier in the pregnancy somehow, then I suppose she could develop enough antibodies to cause a problem for that first child.
