If I am A- blood type then what are my parents' blood types?
We are looking for the possible blood types of a baby.Available information:Baby type A neg -- this may be AA or AO with Rh (--)ABO: must receive A gene from at least one parentRh: must receive Rh (-) gene from both parentsBaby receives one gene from each parent: Note: parents can be Rh (++) or (+-), but we know baby gets (-) from each.Mom AA/AO + Dad AA/AO = Baby Type AA, AO, OOMom AA/AO + Dad BB/BO = Baby Type AO, ABMom AA/AO + Dad AB = Baby Type AA, AO, AB, BOMom AA/AO + Dad OO = Baby Typw AO, OOMom AB + Dad BO = Baby Type AO, BB, BOMom AB + Dad AB = Baby Type AA, AB, BBMom AB + Dad OO = Baby Type AO, BOThere are a lot of combinations for the parents of an A neg baby. To narrow it down, if the parents are not available, then a survey of the blood types of the grandparents would be the next step.
Which blood types cannot produce a child with blood type o?
Several ways, and here is why. First, some definitions. PHENOTYPE is how the trait is physically displayed in the person, so a person's blood type is actually their phenotype. GENOTYPE is the pair of genes that a person carries that determines their phenotype. A RECESSIVE gene is one "trumped" by a DOMINANT gene in the genotype; for blood typing, O is the recessive gene and A and B are dominant. For a person to show the recessive phenotype, they must carry BOTH recessive genes. So, in order for the baby to be type O it must carry two O genes and have genotype "OO". The baby will inherit one gene from the mother and one from the father and, as explained above, both must be O genes. Obviously, a parent with type O blood will pass on an O gene, this is all they can do. But there is also a chance a parent with type A or type B blood can pass on an O gene. This is because a parent with genotype AO will be type A (remember, the A gene is DOMINANT) but can still pass on the O gene. Same with a parent having genotype BO. Only a parent with AB blood cannot have a type O child since they must pass on the A or B gene (in other words, they have no O gene to give).
Can a baby have the mother's blood type?
The two AB parents could have any of an A, B or AB, but not O.The two A parents could have either A or O children, but not B or AB.The two B parents could have either B or O children, but not A or AB.The two O parents could only have O children; they cannot have have A, B or AB.If both parents have rhesus-negative blood, so will their children. If both have positive, the child might be either.
If a baby was born with b neg and mother have o pos blood type what will happen to the baby?
The baby can be either B or O and can be either positive or negative, so either B+ or B- or O+ or O-, O+ is the most common blood group, so statistically this would be the most likely, but the others are all genetically possible. Blood groups are just like other genetic traits, there are dominant (A & B) and recessive (O) types. So, anyone who is A is really Aa or Ao and anyone who is B is really Bb or Bo. One of each of these is passed on to the baby, one from mom and one from dad. Someone who is O is really OO (O is recessive, so it takes two).
Can a parent with ab blood type have a child with ab blood type?
We are looking for the possible blood types of a PARENT.Available information:Mother type AB --can only be AB = contributes A or B geneBaby type O -- can only be OO = has to receive an O from each parentBaby receives one gene from each parent: Mom type AB + Dad type AA/AO = Baby type AA, AB, AO, BOMom type AB + Dad type BB/BO = Baby type BB, AB, BO, AOMom type AB + Dad type AB = Baby AA, AB, BBMom type AB + Dad type OO = Baby AO, BOGenerally, since the AB parent cannot contribute an O gene, baby cannot be OO or Type O. HOWEVER: There is more to ABO blood typing that just the ABO gene.There is also an inhibitory gene that will change any genotype into the phenotype O.Therefore a person with genetically AB blood can be tested as having Type O.If the baby's inhibitory gene has been turned "on", then no matter what ABO genes he receives from his parents, he will test out as a Type O.
If the mom is o and the dad is a what blood type will be their baby?
The baby will either be blood type O or Type A
Mom's blood type is O- Dad's blood type is O plus Can Baby's blood type be A plus?
No, because O is recessive. So, the mom and dad both have OO alleles for blood types. Due to that, they each have to give the baby an O allele, so the baby will be OO.
What will baby's blood type be if mom's is AB and dad is o?
Could be anything, we get our blood group from either parents or grandparents.
Can a woman with type a rhnegative blood have a healthy baby with type b rh positive blood?
We are looking for the possible blood types of the FATHER.Available information:Mother type B -- can be BB or BO = contributes B or O geneBaby type A -- can be AA or AO = must recieve O from mom & A from dadBaby receives one gene from each parent: Mom is BO and Dad is AA = baby AO or ABMom is BO and Dad is AO = baby AO, AB or OOMom is BO and DAd is AB = baby AO, AB, BBIf the mom is heterozygous Type B, and the dad is Type A or AB, then they could have a baby who is Type A.
Can a mom a blood type and a dad with b blood type have a child with o blood type?
yes
Can parent ab positive and b positive have ab negative baby?
Yes! We each have two blood types. One we get from our mother and one from our father. The O type is recesive and only seen if both of your blood types are O. Let's say that Mom is AB+ and Dad is B+. We know that mom's two blood types are A and B. She received one of each from her parents. We know that one of Dad's blood type is B. For him to be just B he carries either a second B or an O. Carring an O without a second O would cause him to have the B blood type. So we know that baby must have gotten his A from mom and his B from dad. If dad's type was BO baby could have gotten the O which would have made him AO giving him an A blood type. The same is true with + or -. The negative is an absence of an anti body on baby's blood. Once again baby has two genes that determine this. One from mom and one from dad. If one of baby's genes is for + and the other - baby will be positive. So even though both mom and dad are positive they can each carry a -. If they both passed their - to baby he will be -.
What type will baby be when mom is o- and dad is o plus plus?
If mom is O- and dad is O+, then the baby can either be O- or O+
If dad has blood type A and mom has blood type B can they have a child with blood type O?
Yes. Type O blood requires that you have two recessive genes, one from each parent. Each of your parents can carry one of these and have a different type of blood. In this case, there is a one in four chances of the child having type O blood.
Is it possible to have a child with blood type O if the mom has blood type A and the dad has blood type B?
yes
Barack Obama's blood type?
Barack is type AB, so there are several possibilities: Mom A, Dad B Mom B, Dad A Mom AB, Dad A Mom AB, Dad B Mom A, Dad AB Mom B, Dad AB Mom AB, Dad AB
What if your parents has blood type O you have blood type O and the father is A what would be the babies blood type?
The infants blood type will be in the O's because o is a recessive jean A and b are dominate jeans meaning you get 1 jean from each parent so say dad was A he cauld have a recessive o ex Ao and mom is Bo dad gives A mom gives b blood type is AB dad gives A mom gives o Blood type is A but o is still in genitic makeup. ex Ao Both parents must contribute o for bloodtype to be o mom must be oo dad must be oo so baby must be oo. As for positives and negitaves IDK. PS I am only 13 but I know a lot so I am 100% sure of the answer. the infants blood type is probably going to be blood type O
Does it matter if the blood types are negative can an O negative and A negative have an o positive baby?
my mom is A - MY DAD IS 0 + Ive always curious how could i be A + is my dad my real dad? I know my mother had affairs so im really curious.sincerely,vikkiyes he could be your father! So If your mom's blood type is A expressed as IAIA(sorry I can't do superscripts) and your Dad is IoIo then when they combine all of the off spring of these two individuals would have type A blood If your mom's blood type was IAIo then the probability of the off spring having type A blood is 50% and 50% probability that they would have type O
