If mom has blood type B and dad has blood type O what is the child's blood type?

The baby will have either type A or type B blood.
If the mother is +\- for the Rh allele, the baby could be positive or negative. If she is ++, then the baby can only be positive (positive is dominant). My husband and I are both positive, but our baby is negative, so we must both be +\-.

∙ 15y agoThe baby could be type A or type B: the chances are equal.
Dad, having blood type AB, must have the genotype IAIB. In other words, he has two different alleles of the blood type gene, equally dominant.
Mum, having type O, is showing the recessive phenotype. So her genotype must be ii (homozygous recessive, i.e. she has inherited two copies of the recessive allele).
Dad will produce (virtually) equal quantities of gametes containing the IA and the IB gene. Mum's gametes will all carry the recessive (i).
So there is a 50% chance of a baby being IAi (blood type A), and a 50% chance of him or her being IBi (blood type B).

∙ 13y agoTo begin with, mom needs to know all the precautions she needs to take during the pregnancy. I am not a doctor, or specialist...just a curious mom of three with negative blood that likes to write, especially when it's a good cause.
KEEP YOURSELVES INFORMED LADIES. I have known people go to free clinics or centers with inadequate health care and they are not even blood typed! THAT MEANS THEIR BABY COULD HAVE LEARNING DISABILITIES, a multitude of problems, or you could even miscarry the baby. All due to inadequate healthcare because they are poor. I have had rich women write to me saying this is a waste of time, everyone knows it....but check out my comments, heartbreaking because these women did not know they should have been given Rhogam at 28 weeks of pregnancy, and then after the pregnancy to protect the next baby.

Best of luck, any questions, feel free to write. Sincerely, Ren

∙ 14y agoAny baby born of these parents could be either type A or type B since they will inherit one recessive (O type) allele from the type O parent and one of the two alleles (A or B) from the other parent. They cannot be the same blood type as either of the two parents:)

Know i'm a decade late to this question but the child will have either blood type A or B the likeliness of the child have blood type O decreases because one parent already has both A and B. that's why if the parents had type A and type O or type B and type O then having type O is possible

∙ 15y agoThis is impossible to say because you have only given one blood type. The negative and positive apply to a different marker, known as the Rhesus marker.

∙ 15y agothe baby will either be A+ or B+ but it will be heterozygous A or Heterozygous B

∙ 14y agoThe child can be type B or O, depending on the mother's genotype.

∙ 14y agoThe baby could either have AB positive or AB negative blood.

How does a baby have o blood type and mom has ab and dad has b?

How can siblings have different blood types?
Blood type can vary from person to person even if you are their brother. It has nothing to do with relation. When chromosomes recombine during conception, the blood type is written in the DNA and this can be a match of the father or mother or even a random cross between the two.
Can a blood type b negative man father a blood type a positive child?
yes, if the mother is either A positive or AB positive.
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 mom a blood type and a dad with b blood type have a child with o blood type?
yes
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
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
Is it possible to have a child with blood type O if the mom has blood type A and dad has blood type B show your work?
Yes.
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.
Should you have the same blood type as your mum?
Not necessarily, you could have the same, you could have the same as your dad, or you could be different. If your mom had type A blood and your dad type B you could possibly have type A, B, AB, or O blood.
Why do you have the same blood types in your family?
Genes and traits get passed just like if your dad had bbrown hair and your mom had blonde hair you would either have brown or blonde so you either get your dad's family blood type or your mom's family's blood type
If mom has negative blood type and dad has positive blood type is it true that all the babies you have will be the same gender?
LOL Not true
Mom has a positive blood type dad has b negativeblood type can it produce a child with o positive blood type?
Since O blood is recessive and B is dominant, this scenario would be possible
What blood type would a child have if dad is A positive and mom is O positive?
o
If you have a mom with blood type A plus and a dad with blood type A plus what blood types could you have?
You could be A positive, A negative, O positive or O negative.
