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 +\-.
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.
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.
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.
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).
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.
yes
yes
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
The baby will either be blood type O or Type A
Yes.
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.
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.
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
LOL Not true
Since O blood is recessive and B is dominant, this scenario would be possible
o
You could be A positive, A negative, O positive or O negative.
