Can type a and o make AB?

And so is AB blood type. But someone who has a B and an O version only makes the B protein. They are B blood type but can pass the O onto their kids. So two B parents can make an O child if both parents are BO….Menu.

Genes	Blood type
AA	A
AO	A
BB	B
BO	B

Can type O and type AB have a child?

An AB and O couple producing an AB child cannot be explained in terms of the usual inheritance patterns. One would not expect the cord blood result to be AB when the mother is type O, however, in very rare instances, such as the cis-AB blood type, it is possible.

Can parents with AB and a blood type have a child with O?

An AB parent can indeed sometimes have an O child. But it is by no means common. In fact it would be fair to say that it is exceedingly rare. Usually, an AB parent and an A parent can only have children who are Type A or Type B.

What is the genotype of type A and has a Type O parent?

genotype OO
A person with blood type A could have the genotype AA or AO. A person with blood type B could have the genotype BB or BO. A person with blood type AB as the genotype AB. And a person with blood type O has the genotype OO.

Can O+ and AB+ have a baby?

In most cases, an O parent and an AB parent will have only A or B kids. I added a table at the end of this answer that has all blood type combinations for two parents plus the possible blood types for their children. Exceptions to these rules are extremely rare.

Could a man with blood type O be the father of an AB child?

Answer and Explanation: A man with type O blood would not be able to produce a child with type AB blood regardless of the mothers blood type.

What blood type does O and AB make?

Can AB+ father and O+ mother have a baby?

If a father’s blood group is o+ and mothers’s is AB+, what would their children be? The genotype of the father or possible genes he could pass on would be O O; the mother, A B. The genotype of the children would be AO & BO.

What blood type does AB and O make?

One Shall Pass (I made the mom AB and the dad OO here but it works the other way too.) What this means is that each of your kids will either be BO (the B from you, the O from your partner) or AO (the A from you and the O from your partner). They can only have an A or a B blood type!

What blood type or types can be found in an offspring if a mother has type O blood and the father has type B blood?

A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter. This couple could have children of either blood type A (O from mother and A from father) or blood type B (O from mother and B from father).

Is blood type O and AB compatible?

Donors with blood type AB… can donate to recipients with blood type AB only. Donors with blood type O… can donate to recipients with blood types A, B, AB and O (O is the universal donor: donors with O blood are compatible with any other blood type)

Can blood type O give birth to AB?

A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter….How are ABO alleles inherited by our children?

Inherited	Blood type of child
O from the mother B from the father	B

What is the blood type of the father if the daughter is type O and the mother is type A?

Can a man with O blood type be the father of an AB child?

Is O+ and AB+ compatible?

O positive red blood cells are not universally compatible to all types, but they are compatible to any red blood cells that are positive (A+, B+, O+, AB+).

Could a man with type AB blood be the father of an O child?

In cases of questioned paternity, ABO blood-typing can be used to exclude a man from being a child’s father. For example, a man who has type AB blood could not father a child with type O blood, because he would pass on either the A or the B allele to all of his offspring.

How do you get blood type O?

Who can receive O positive blood? Anyone with an Rh positive blood type can receive O positive red blood cells – so that’s A positive, B positive and AB positive as well as O positive.

What would a child’s blood type be if the mother is type O and the father is type A?

ABO Blood Type The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A. For instance, a parent with O blood with 2 O genes and a parent with A blood with 2 A genes will have an A blood type child with one A gene and one O gene.

Is AB and O compatibility?

People with type O blood will react against type A, type B, or type AB blood. People with type AB blood will not react against type A, type B, type AB, or type O blood.

Which blood groups Cannot marry?

When a mother-to-be and father-to-be are not both positive or negative for Rh factor, it’s called Rh incompatibility. For example: If a woman who is Rh negative and a man who is Rh positive conceive a baby, the fetus may have Rh-positive blood, inherited from the father.

Can a blood type AB/O couple have AB and O Children?

Can a blood type AB/O couple have AB and O children? The claim that blood type AB people cannot have blood type O offspring and vice versa is false. There is a phenomenon called cisAB where both, the A and the B are encoded into one allele.

What is the ABO blood type of the father?

The ABO blood type of the father if the blood type of the mother and the child are known (bottom chart). ABO blood types can be complicated to understand. This is mostly due to the fact that the ‘O-type’ antigen is masked by the presence of an A- or B-type antigen.

What is the phenotype of a parent with an AB allele?

When one parent carries a Cis AB allele, the other allele can be any of O, A or B and the phenotype of this parent is always AB, but the children will inherit either the AB or the other allele from this parent.

What does it mean to have an O blood type?

People with an O blood type have two copies of the O version of the gene (though there are rare exceptions to this rule). I have shown him as OO. Dad will always pass an O to his kids (that is all he has to give!) and mom will pass an A half the time and an O the other half of the time.
