What else can I help you with?
If the baby's father is A negative and the mother is o negative what will the baby have?
This will depend on the genotype of the father, but either A negative or O negative.
If the mother has type O positive blood and father has type AB positive the baby has type A negative where does the negative come from if both parents are positive?
The baby could be A Positive, A negative, AB positive, AB negative, B Positive, or B Negative. In order to know the baby's blood type, you need to know the parent's genotype. From this information, I know the father's genotype. The mother's genotype is unknown. All I know is her phenotype. Since there are two alleles for these genes, Mom's genotype could be AO Positive, AO negative, AA Positive, or AA negative. Since the father is AB Negative, both of his alleles are know. One is coding for the A antigen and the other for the B antigen. Since he is Rh Negative, neither of his alleles is coding for "usually only Big D is tested" is coding for the Rh factor. The mother however is A Positive. That is her phenotype. Her genotype could be any of the ones listed above. There is a fifty fifty chance that she could pass on either allele. If she passes on the allele for Rh positive, the baby willl be Rh positive even though the father is Rh negative.
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 a O positive and B negative produce baby A negative?
Yes. The long answer is to distinguish phenotype (the blood type A, B, AB, O) from genotype (what pair of alleles compose your genes (AA, AO, BB, BO, AB, OO). The same goes for Rh factor (positive or negative), although the theory is more complex. The Rh + is usually taken to mean positive for the D antigen. So parents having O (must be OA genotype) and B (must be BO genotype) blood can have a child with A ( will be AO genotype).
What blood type a baby will be if father is a and mother is o?
The genotype of the father is certainly OO (because blood type O is recessive). The genotype of the mother however can be AO or AA (both give blood type A). The baby will have a combination of the genes from the mother and the father (one of each) and so: - If the genotype of the mother is AA and the genotype of the father is OO, the baby will certainly have AO as genotype and has therefore blood type A. -If the genotype of the mother is AO and the genotype of the father is OO, the baby can have AO or OO as genotype. AO results in blood type A and OO in blood type O (50% chance).
When can one know the baby genotype in the womb?
We can detect genotype as early as 10 weeks gestation.
How do you know your baby's genotype in the womb?
It is possible to know about your baby's genotype in the womb. If one has a great deal of money, they can pay a doctor to do special testing on the fetus.
If father has blood type B positive and mother has blood type A negative what may be the blood type of the child?
The child may be any blood type, depending on the genotype of the parents. If, for example, the father's genotype is BB and the mother's is AA, then the baby must be type AB. If the father's is BO and the mother's is AO, then the baby can be any type.
Will a mother's blood produce antibodies if the mother is B positive and the baby is B negative?
The mother will be given Rhogam injection within 72 hours to prevent formation of antibodies to protect the 2nd baby that he will be conceiving.
Can a mother with O negative and a father with b positive have a baby with o positive?
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.
What blood type a baby will be if father is o and mother is a?
The genotype of the father is certainly OO (because blood type O is recessive). The genotype of the mother however can be AO or AA (both give blood type A). The baby will have a combination of the genes from the mother and the father (one of each) and so: - If the genotype of the mother is AA and the genotype of the father is OO, the baby will certainly have AO as genotype and has therefore blood type A. -If the genotype of the mother is AO and the genotype of the father is OO, the baby can have AO or OO as genotype. AO results in blood type A and OO in blood type O (50% chance).
If a mother's blood type is A positive and the baby's blood type is O negative what blood type could the father have?
The father's blood type must be O, Rh genotype can't be determined.
