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 +\-.

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

A baby with O blood type can be born to a mother with AB blood type and a father with B blood type if the mother is a carrier of the O blood type allele from a parent and passes it on to the baby. The baby inherits one O allele from the mother and one B allele from the father, resulting in O blood type.


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.


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 blood type b negative man father a blood type a positive child?

Yes, it is possible for a blood type B negative man to father a blood type A positive child. The ABO blood type system is inherited from both parents, with each parent passing on one of their two ABO genes to their child. This means that the child could inherit an A gene from the mother and a B gene from the father, resulting in a blood type of A positive.

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.
