Can a child have AB blood if both parents are O?
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 |
Can you get AB blood from A and O?
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 2 O+ parents have an AB+ child?
But it is technically possible for two O-type parents to have a child with A or B blood, and maybe even AB (although this is really unlikely). In fact, a child can get almost any kind of blood type if you consider the effect of mutations. How does this happen?
Who can give blood to AB+?
What are the major blood types?
| If your blood type is: | You can give to: | You can receive from: |
|---|---|---|
| AB Positive | AB+ Only | All Blood Types |
| O Negative | All Blood Types | O- |
| A Negative | A-, A+, AB-, AB+ | A-, O- |
| B Negative | B-, B+, AB-, AB+ | B-, O- |
How do you get AB blood type from parents?
How are ABO alleles inherited by our children? Each biological parent donates one of their two ABO alleles to their child. 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.
Can two O blood types make AB?
Two O parents will get an O child nearly all of the time. But it is technically possible for two O-type parents to have a child with A or B blood, and maybe even AB (although this is really unlikely). In fact, a child can get almost any kind of blood type if you consider the effect of mutations. How does this happen?
Can an AB parent have an O blood type child?
Yes they can. 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. The one exception is in certain Asian groups. Some of these folks have a rare version of the ABO blood type gene called cis-AB.
Can two people with A and B blood types have a child?
One parent with A and another with B can produce a child with A, B, AB or O blood types. If one parent has A and another has AB, they can either produce a child with A, B or AB blood types. If one parent has A and another has O, they can either produce a child with A or O blood types.
Why can’t I have an O child if I have AB?
The reason why an AB parent usually does not have an O child has to do with how blood type normally works genetically. Remember, we have two copies of each of our genes – one from mom and one from dad. This is true of the blood type (or ABO) gene as well. The ABO gene comes in three varieties: A, B, and O.
What blood type can a father pass to his child?
Mother with AB blood type can either pass the A or B allele to the baby. Likewise, a father with O blood type can only pass O allele to the baby. If both parents belong to the blood group O, the child will also belong to the O blood group. Two A blood group parents can give their child either A or O blood group.
